First of all, let me say what a wonderful photo you have. A treasure for sure. I have no reason to believe your Welke is connected to my Welke line, but there are a lot of puzzle pieces missing. Do you have any idea where in Russia, Russian Poland, or Volhynia? I am not aware of the immigration of any of my Welke line except my father and his siblings. The first came in 1913, the rest of the family was caught up in WWI, the remaining orphaned siblings, my father and three others came in 1920. There were other Welkes at that time and I found some were still there in WWII. I don't know what happened to any of them. It's entirely possible they immigrated, but we don't know when or where. My Welke line is pretty much from Dubeczno,Wlodowa, Lubelskie, Poland and that area.
