In US, John (Johan) married Mary Meyers/Myers/Meiers, June 18, 1888 They had Clara, Theresa, Isabella, Charles. Son George from previous marriage came to US with Uncle Karl. I have a sheet somewhere with dates. Misplaced my binder...
Charles m. Marie Halterman. They had Charles, Richard, Norma, Mary. My line is John&Mary>Charles>Richard>Linda.
I received documents from Sweden from Arne Strang. I believe he said he use to be a librarian. I would have it in the documentation.
Off the top of my head. I think that Johan Alfred had a sister in law who moved to streator, IL and married. I think the last name was something like Bergmann, but would have to check. I haven't had the opportunity to research this any further. I think that marriage is on the LDS site, and possibly IL marriage records online.
There are Frandins in Kansas, Nevada, Illinois, and Idaho. I have touched base with several.
Let me know if anything here lines up with your stuff. My great aunt says the name was pronounced "Frendeen".
