Johannes first wife was Cora Lundstra of New Jersey. I have an obituary of Daniel J. VandenBroek, Anna's brother, and it says that he was survived by Mrs. Henry Munday of New Jersey....so Annie's married name is Munday. Is that your Annie's married name?
I do have a translated copy of Johanne's book in which he says a lot about his first wife, Cora. If you want a copy, please let me know and I would be happy to mail it to you.
