Genealogical uncertainty

Many of us are avid genealogists who want to trace our ancestry as far back as is reasonable in all lines. When filling out our family trees, we come to some dead ends where lack of information blocks us from going back further. We may also come to situations where there is some information relating to the parentage of a known ancestor but not enough to claim certainty.

I have several uncertain situations in my American ancestry. For example, I have a tantalizing possible descent from the Mayflower passengers Stephen and Elizabeth Hopkins and Francis Cooke; all three would be new Mayflower ancestors for me if a link supported by circumstantial evidence (discussed in Dawes-Gates 2: 492) is correct.

The hazard in dealing with any situation with uncertainty is that there is a temptation for appealing possibilities to become probabilities and appealing probabilities to become near certainties. However, overly zealous avoidance of this hazard can lead to throwing away information, and I hope to show here how nuggets of certainty can in some cases be extracted (without compromising integrity) from situations of uncertainty.

Let’s imagine that you know the father of a particular female ancestor but are uncertain about the mother. Specifically, suppose that the father had two wives, and you don’t know (and can’t easily find out) which of them is the mother of the daughter. How will you deal with this uncertainty?

A less restrictive approach would be to “peek” at the ancestry of the two wives…

If you are entering your genealogical data into a database or writing an account of your ancestry, you will no doubt report some data about both wives, but how far will you delve into their ancestry? The most conservative approach would be to report their parents and go no further until you find new information which might help you decide which wife is likely your ancestor. A less restrictive approach would be to “peek” at the ancestry of the two wives and begin to satisfy your natural curiosity about the new ancestors that each of them could add to your family tree.

However, I will advocate here that even before the uncertainty is resolved, there is no disadvantage in researching and reporting as much of the ancestry of both wives as can be traced. Especially if the uncertain mother appears a number of generations before the root person (e.g., you) in generation 1 in the family tree, the extra work in tracing both potential mothers is not particularly great. For example, if the uncertain mother is in generation 7 and there are no other uncertain parents in that generation, then when working on tracing all branches of the ancestral tree, you would be researching 65 people in that generation rather than 64.

In particular, in this two wives situation a potential benefit in tracing the ancestry of both wives is that they might be cousins of some sort. Suppose they are third cousins, having two great-great-grandparents in common. Assuming there are no mistakes in the paper trail which supplies the cousin relationship, the shared ancestors of these two wives are definitely ancestors of yours (or whoever occupies the generation 1 slot in the family tree on which you are working), independent of which of the two wives in generation 7 is the mother of your ancestor in generation 6. This is a nugget of certainty which you can extract from the uncertainty connected with the question about which of the two wives is your ancestor.

If one or more of the shared ancestors of these two wives were participants in some significant historical event, you might be stimulated to learn more about this event, given that you know you are descended from some participants, even if you don’t know the exact routes.

“We haue the rather noted these thinges, that you may see the worth of these things…”

Further, consider the apparently even more tenuous case where you don’t find any common ancestors shared by the two wives, but you find ancestors of those wives who have had some shared experiences. For example, wife 1 may be descended from Mayflower pilgrim A and wife 2 may be descended from Mayflower pilgrim B. In that case you can read William Bradford’s Of Plymouth Plantation knowing that it chronicles the saga of one or more of your ancestors, and in so doing you will be potentially fulfilling some hopes expressed by Bradford: “We haue the rather noted these thinges, that you may see the worth of these things, and not necligently loose what your fathers haue obtained with so much hardshipe.”[1]

Don Stone is a retired computer science professor. His interest in genealogy began at the age of 13 when his mother told him that he was descended from the artist John Trumbull. Some library research quickly revealed that he was descended from the artist’s brother, but he was hooked on the subject. Don enjoys researching modern, medieval, and ancient genealogy and making large-format illustrated genealogical charts. He received a Bachelor of Engineering Physics from Cornell University and an M.S. (Computer and Information Science) and a Ph.D. (Instructional Systems) from the University of Pennsylvania.

  1. I wonder if we have a relationship. I am working on the Whitmore line and have connections to Cornwell/Cornwall, Hall, Harris, and Johnson in Middletown, CT. Francis Whitmore, b. 1650 in Cambridge, Mass., was one of the first settlers of that town, arriving in 1672. The Whitmores stayed many generations.

    1. If Elizabeth Johnson is the wife of my likely ancestor Hamlin John Hall, then I would be related to the Harris and Cornwell/Cornwall families by marriage. I don’t know of any relation to Whitmore.

      1. The only Elizabeth Johnson I have was born about 1679/80 and married to John Blake.
        I have three Elizabeth Halls, one of whom was born circa 1720, and married Seth Whitmore in 1745. I don’t have the names of her parents. Seth died in 1748, so it’s possible she married Hamlin John Hall [perhaps her cousin?] a year later, but one would think the marriage record would have listed her name as Whitmore.
        All in all, I think this is a long-shot. But there might be other connections with your family — there were few marriageable options at the time and lines are entwined.

  2. Far above Cayuga’s waters, your advice is what I have been doing since I realized how often the wives are related, sometimes even sisters. But also, if there are children by the other wife, those people are your cousins, and they may have married into descendants of your unknown lineage. How often do we figure out a line by tracing the brothers and sisters, and yet so often, the beginner only looks at their own ancestors in the direct line.

  3. I have one of these situations, not so far back (1860-1870), where I know all the children and have tracked them via their marriages, etc., and I know for certain that the first four children (including my g-g-grandmother) were from wife 1. And I know for certain that the last child was from wife 2. there are, I think about 5 children where the correct mother is the question. No birth records, a possible death record for wife 1 that just doesn’t work time wise. Also no marriage records. This is in Charleston SC. I am in hopes DNA will help figure out who goes with who but so far that hasn’t panned out even though I have found cousins from at least 3 of the lines. I keep working away at this in hopes that some day there will be some document to help me.

  4. Just the other day, it occured to me that Robert Smart’s widow Mary could be related to the husbands of two of his daughters. She is very likely Mary Glidden, daughter of Charles and Eunice. To my knowledge, no one has thought of this possibility before I did the other day.

  5. I have always taken this approach (tracing ancestry of both wives), and the advent of genetic genealogy now offers the possibility that we might eventually have answers. If a large number of cousin genetic matches connect to ancestry with wife 1 and none to the ancestry of wife 2, it may help resolve the question,

  6. I have been working on my Marshall gg grandfather’s parents for 3 years. I tracked him from a city directory in Buffalo ,NY in 1850 to Eaton Rapids, MI with the first known Marshall name associated with him.
    Through land records and a will…I tracked him to Chardon,Geauga,OH.
    There, I found an indenture record for an Amos Marshall , born in 1827…which matches the birth year he gave in all of the NY and National Census records.
    I found several Marshall families in Geauga county, and one living in Chardon.
    I researched every family. ..and traveled to Chardon twice to go to the archives.
    With the assistance of Claire Wilson, head archivist…I figured out that there were 4 John Marshalls there…and the man who I am now convinced is my ggg grandfather. ..William Obediah Marshall Sr.
    However, the research was muddied by a court case in March of 1828….where the Marshall family blew apart and the children of the first marriage were sent to live with other families in Chardon.
    I had a theory that my gg grandfather was the product of incest! I’m now convinced that I am correct, and I am also convinced that I know which of the 2 daughters is my 3rd great grandmother. ..and I know that my 4th great grandmother is the first wife, Mary “Polly” Drew.

    I have found 2 cousins who have been told that there was incest …and one confirmed that both daughters had had a child by their father!
    Court records found in the archives established dates…and only the one daughter could have been Amos’ mother according to the dates given.
    This daughter ended up in an insane asylum…now I am trying to find out what happened to her…and where she lived and died.
    I only know that he tried to hide her in MALDEN ( MA ?) so she couldn’t testify against him in the court trial.
    This from a newspaper reprint in the Trump of Fame newspaper, Warren Ohio.
    I’m also trying to find out more about William Obediah Marshall’s War of 1812 military history..as he was evidently at the battle of Fort Erie and taken POW. He was listed as DISABLED.
    Also, I am sure that DNA results are going to be affected by this event…but I am not sure how to figure it all out.
    Any research assistance GREATLY APPRECIATED!

  7. Don – Excellent points made throughout. I try to make it a point when I have a potential candidate for parents to follow the possibility upstream in hopes that I may find some evidence to support the hypothesis, just like checking out spouses of siblings.
    I am intrigued by the Mayflower possibilities you mentioned. I am following a potential lead for the parents of a 4th great grandmother of mine. If my hypothesis is correct, then the father would be a known descendant of the Hopkins’, Cooke, and both Rogers as well. All would be new to me as well. Perhaps we are distantly related. Thanks again for the superb information.

  8. Thanks for affirming this strategy, which I, too, have used when encountering such uncertainty and similar strategies when examining brick walls. Careful notation and continued good research can provide valuable leads for our individual research and for others working with affiliated lines. I appreciate your reasoning.
