Bertha would be my ggg-grandmother (to the best of my knowledge). Her son Hans Jacob is my gg-grandfather. I have lots of info on his family and copies of Hans' death certificate and obit.
I have a note that Bertha Ingelsdtr FEVIK's parents were Ingel FEVIK and Berthe Andersdtr, but no confirmed sources.
Happy to share what I do have! And would love to know what you have on Herman Guttormson and Bertha's family.
