I didn't even notice the man listed below Wilhelmina(Minnie/Mina)and her children or that he was also going to meet Jacob. Thank you so much for pointing that out!
We were told by my grandmother that Minnie's maiden name was Rapin (or Rapine, not sure on the spelling). Jacobs birth date was also told to me by my grandmother. Unfortunately, I don't know when Jacob and Minnie were married or very much at all about the Kayma family. My grandmother is now deceased so I cannot ask her either.
I too was researching the area Jacob and Minnie were from and had learned it was a mining town, which makes sense since that was Jacobs occupation in Pennsylvania.
It was so great to hear from you and thanks for sharing your info with me!
