Samuel A. Stainbrook is part of my lineage. I had a large amount of information on the Stainbrook line but unfortunatly I lost my database in a computer crash. All the information on the Stainbrooks I attained came from my grandmother. She has a lot of documents from the Stainbrooks and if memory serves me correctly, I believe she has the civil war muster papers from Samuel. What I can tell you is that more than one Stainbrook served in the civil war and the family came from Germany and changed the name to Stainbrook to "Americanize" it. In Germany the surname was Stein Bruchel. I will be getting all the information from my grandmother again in order to rebuild my database. If you want, email me at firstname.lastname@example.org and I will see what else I can tell you.
