Original poster, Thanks for responding. A really good lead for a Sarah "Sadie" Sanasac born 1888 in Minnesota was posted. I followed up so that we could rule her in or out as a candidate for "your" Sadie. Ended up ruling her out, as you can see.
We know about Robert Armstrong - got it.
I don't know what you mean about the rest of your reply. Who is the John Senasac who was a Civil War soldier? Who is Cypriem Senasac? Are you referring to people on your family tree, or people who are mentioned in your family stories?
So far what you have said is that you have a Sadie Senesac b 1888 in Minnesota whose death certificate gives her parents as John Senasac and Frances Breaders. She married Robert Armstrong. She died in 1940 and is buried in Nacodoches county, Texas.
That's an interesting find and there could be a connection, in fact it seems likely. John Senesac (or his wife) has to be in Minnesota in about 1888 for "Sadie" to be born there. I imagine Sarah Gray Crisp Senasac was in Texas at that time. If we knew why the original poster mentioned a Civil War soldier, that could tighten the link to your find.
