Actually I am not sure when Ludwig came to IL.I have death certificates for William (my grandfather) and for Fred (his father) who shows Fred's father is Ludwig born in New York.My grandmother verbally told me that he came to IL in 1880 but I don't think she is correct. Fred was born in Okawville2-26-1857.
I have the death certificate for Caroline (Brink) Brockschmidt that shows her mother was Caroline Komena and her father was Louis Brink. My grandmother told me that these two were both born in Germany, but no proof of that either.
Its interesting that you mention Aufenbrink. I had never thought of looking in that direction.
I just tonight found another site that lists information from the Ebenezer Luthern Church and I believe my g-g=grandfather (Ludwig) was a member of that church. He is buried in that cemetery.Not sure that is my Ludwig.
