Thank you for your reply to my query.
I have not had much success in finding info for Alt Messer (Ust Zolicha) or Neu Messer (Lysanderdorf) on the internet.
I am wondering where you found Katherine Schmidt as she may well be related to my g/g grandfather Johann Peter. He was born 4 Oct 1848 in Alt Messer and moved to Neu Messer with his parents when he was 15 yrs old. Since there is only a 7 yr. spread between Katherine and J.P. they may well be siblings or cousins?
I would also be interested in Adam Schneider's ancestry. Does it also go back to Alt Messer or Neu Messer? The Ernestina Schneider I seek was likely born in Alt Messer around 1810 - 1830. I have no info on her parents or siblings.
Any additional info you may provide would be very much appreciated.
