Your message states that Andrew Fenske's second wife was named Rosa. Do you have any information regarding who his first wife was? Do you have any info regarding names of any children?
I'm trying to find the name of my great great grandfather. My great grandfather was Hermann Fenske (b. 1856 in Posen, Prussia). His mother was Louise Lieske, but his father says "unknown." Louise married a Martin Baumgart, but Hermann always went by "Fenske." Obviously, he knew who his father was, whether he was born out of wedlock, etc. (divorce was unheard of at that time, yet not impossible)
Any info appreciated. Thank you.
