Pieces are starting to come together for me with respect to my adopted grandfather who was a Semler by birth.With what you've posted, as well as others, combined with some other census information and family records, there are connections between your Semler's and mine.
What I know is that there was a Lewis Semler born in 1884 who was living with Sophia Rupp Semler (widow of Lewis 1828).The age difference indicates that the younger Lewis was not Sophia's son, but perhaps a grandson or nephew.
The 1900 Census shows a Scott M. Semler living 2 houses away from Sophia's household.Scott's children were Austin Brown, Scott Marion, and Olive.
Now, my grandfather was born after the 1900 census, but my father clearly recalls meeting his brothers Austin, Scott, and Lewis.The Lewis throws me -- I think my dad is wrong about Lewis being a brother, but, heck, they were only 2 doors away and probably the "cousins" played together as brothers.
The census shows Sophia as a "brick manufacturer" and Scott M. as a "brickyard manager".Makes sense when you look at the "masons" that Jacob's sons were.
What I can't figure out is the relationship between Scott M. Semler (1858) and Lewis Semler (1828).What I beleive is that Scott is a son of one of Jacob's sons, probably Gotlieb or Frederick.Since Scott was born in 1828, I think Gotleib is just too old to be the father, so I'm leaning towards Frederick.Of course, Andrew wouldn't be completely out of the realm of possibilities.In any case, this would make Lewis (1828) the uncle of Scott M. Semler.
I also believe that the Lewis who was living with Sophia Rupp Semler in 1900 was Sophia's grandson to one of Sophia's sons who may have died.I think his name was George Semler, and I think George died before 1900, but I haven't proven this yet.Frankly, I can't remember how I came up with George, except that perhaps my father may have mentioned that there was old man George in the family. He also thought there was a David, but I haven't found him yet.
What do you think?Can you collaborate any of this information with your Semlers?
