I don't see the connection of your Yankel to the Jacob or Yacov Peretzman that I research. If your Yankel was 32 in 1876, he was born about 1844, which would match my Jacob or Yacov Peretzman. But my Yacov/Jacob married Jeanette Schmidt, who was born abt. 1853, same age as your Nekhama, but the names aren't a match.

Could your Yankel Peretzman be a brother of my Jacob/Yacov? Where do you see the connection? Thanks !
