There was a reason why ThruLines at AncestryDNA gave me Ellosif Lowy as a potential mother for Florence Ellen Butler (born in the 1850s, probably in Missouri). Florence Ellen Butler is in my tree as the daughter of a Benjamin Butler.
And a little further digging did indicate that a woman named Ellosif Lowry married a man named Benjamin F. Butler in Vermilion County, Illinois, in 1841. That Benjamin F. Butler was not the same Benjamin Butler who was the father of Florence Ellen Butler. Ellosif (probably a variant of Ella) and Benjamin F. Butler remained in Illinois, settling in McDonough County and living there in at least 1870 when Florence Ellen Butler’s family was living in Union County, Iowa, with a separate family of children. (I’ve made notes in my files on Benjamin why this Ellosif/Benjamin couple is not the one I want).
So ThruLines was making a suggestion of a parentage based upon the name of the father I had in my tree and a match for him in a marriage database–it wasn’t making a suggestion of Ellosif Lowry as an ancestor based on any tree in their files. I was under the impression that ThruLines suggestions of potential ancestors were based upon shared DNA and names in trees.
And the DNA match I have that ThruLines said was suggestive of Ellosif isn’t suggestive of her at all. A comparison of the trees of that DNA match and me shows that the DNA match and I are both descendants of Ida (Sargent) Trautvetter (1874-1939). That’s one of our most common ancestors (the other being her husband George). Any suggestion of an ancestor earlier than Ida is not based on the shared DNA match and is solely based on a tree or other non-DNA genealogical evidence.
