Hi, my grandmother was a Krmpotic at birth. Krmpotic's are from Lika, Croatia. I dont have too much info on their family tree, although I have travelled there often. I know of a brother my grandmother had who immigrated with a cousin (?) around the same time as those noted below. His name was Jure (Jurica / Juraj) Krmpotic.
One big issue about immigration records is that the gov at the time would change spellings, or over time, the people themselves would anglo the name. Dan would have been Dane, Frances was most likely Franjka (which was also my granny's name), Nick would have been Nikola and Rosa, most likely Ruza. as for Thomyonivich - That was probably Tomljanovic - which is also a surname in Lika - so it would make some sense.
I'm in Toronto, I know my grand uncle came through NY and at some stage may have settled in the Nevada area.
Do you have any other info?
Fawn
