Wrapping Up the Becker Research & Sharing Resources

  I'm concluding my research into the Becker/Baker family and their immigration from New York to Canada, and later from Canada to Cleveland. I have made some amazing discoveries along the way, and feel I have a much better handle on when and why they immigrated from place to place. Here are some highlights and important discoveries I made along the way: I located a fabulous original photo of my great-grandfather Edward in a St. Catharines museum! While creating a timeline, I noticed that Joseph Becker's grandfather Peter Schiltz died in St. Catharines, Ontario, not in Sheldon, Wyoming, New York, where he lived. A Belgian cousin contacted me about our common Schiltz ancestors after reading a blog post. I discovered there were two Joseph Beckers in Sheldon, Wyoming, New York, who each had a son named Joseph. While attempting to separate them in land records, I came across the not-my-ancestor Joseph Becker's will in a Wyoming County deed book.  Though my great-great-grandfathe

Timelines & ThruLines: Untangling 2 Elizabeth Butlers in Ohio


by Nancy Gilbride Casey

In her excellent article "How to Evaluate an Ancestry ThruLine," author Nicole Dyer of the Family Locket team offers several practical methods to use when reviewing a ThruLine.1 ThruLines suggests possible ancestors who are in both a user's and their DNA matches' linked family trees. 

Ms. Dyer's methods include noting red flags (such as too little shared DNA), as well as signs of reliability (correctly noted on maternal or paternal side of family, for example), to help determine if a suggested lineage is plausible.2 Her helpful list, as well as the use of a timeline analysis, were useful while disentangling two women named Elizabeth Butler born in the early 1830s in Ohio.

The parents of the ancestor of interest—Elizabeth Butler of Defiance, Ohio—are yet unidentified. However, many Ancestry trees have identified them as Abner Butler and Tabitha Moredock of Clermont, Ohio. The Butler couple was also a suggested as JC's 4x great grandparents in Ancestry ThruLines.

To untangle the confusion, I first created a timeline for the women, noting some key events in their lives. Immediately the differences began to be drawn:

Though not an exhaustive timeline, these few details clarified that there were two distinctly different women named Elizabeth Butler living in relative proximity to each other in Ohio during this time.9

So why did the ThruLines suggest Abner and Tabitha Butler of Clermont as the parents of Elizabeth Butler of Defiance in the first place? ThruLines made the suggestion based on JC's DNA matches who also have an Elizabeth Butler in their trees. In this case, Tabitha Moredock and Abner Butler were suggested as parents to Defiance Elizabeth Butler:
 
 
 

 
In viewing the ThruLines to Abner and Tabitha Butler, I immediately noted one of Ms. Dyer's ThruLines red flags - a lack of matches to siblings of a known ancestor. Dyer writes, "...if the only matches descend through your known ancestor, the most recent common ancestor of the matches is not the ancestor in the Thruline estimate."10 For this ThruLine, there are no siblings listed alongside Elizabeth to also connect to the Butler couple, though they had seven other children.
 
In a contrasting example, consider Defiance Elizabeth Butler's ThruLine: There are 11 different matches among three of her children. Reviewing the shared match pages of each suggested DNA match, the vast majority also match each other, an indication of a genetic network among these descendants. 



In another tip, Dyer notes the amount of shared DNA among matches in a proposed
ThruLine may also indicate a more reliable suggestion. Matches sharing over 15cM may be considered more dependable and less likely to be a false match.11 In the ThruLine for Elizabeth Butler above, JC shares 3465-9cM of DNA with the matches. Of the 11 matches, only four share less than 15cM, with most falling in the 20-36cM range (JC's parent is the high outlier at 3465cM). 

Dyer suggests another test of whether the ThruLine is reliable: If matches are listed appropriately on Mother's Side or Father's Side.12 (This method applies if either or both of the parents of the test taker have also tested on Ancestry.) In this case, JC's father has also tested. Of the 10 matches listed in this ThruLines, six have the "Father's Side" designation. Interestingly, the ones that do not have this designation are the matches sharing less than 15cM, and for good reason: Ancestry does not apply the Mother's Side or Father's Side label to matches under 20cM. However, a review of their shared match pages indicates that even those matches under 20cM in this ThruLine match others labelled Father's Side.
 
Though the search for the parents of Elizabeth Butler of Defiance continues, the use of a timeline to compare the two Elizabeth Butlers helped distinguish the woman from Defiance from the woman in Clermont, Ohio. Applying Ms. Dyer's evaluative tools helped show that the suggestion of Abner Butler and Tabitha Moredock as parents of Defiance Elizabeth Butler was unreliable. In contrast, using the analysis on Elizabeth Butler's ThruLine indicated hers was much more promising, and worthy of further research.
 
Both a timeline and a thorough ThruLines analysis are great tools to pack into your genealogy toolbox.
