Kavalec Family Genealogy Forum
Maybe there could be a connection. Do you know what country or countries Josefa's ancestors came from? If Norway is their country, it could be there is a tie to the Grandma's family. Her family did settle in Minnisota.
Somewhere I have a record of her family names that my Grandma gave me on one of the rare visits I have made to her, about seven years ago. (She lives far away. I did not see her when I grew up, due to my mother's remarriage, but a few years ago we did get in touch, although it is seldom that I have seen her.)
If I find the information sheet that I wrote down her family's names on, then I will write again and let you know if any of our names connect with any of yours. I'll look for the paper this coming week.
