My SVOREN's are from an area in Slovakia called Sumiac. My grandmother's name was Borbala Loucia Svoren (b 14 Apr 1888) and her parents names were Stefan Svoren & Marii Fedor.
She had a sister named Mary.
Grandma married Jan (Sugar) Svonavec on 27 Nov 1905 in Sumiac. They both came to the United States in 1909 & 1910.
The town Grandpa was from was Muranska Zdychava.
I have not been able at this point to find out much for information on the surname Svoren. Other Svoren's I have found on the internet appear to be from Scandinavian areas.
As far as I know, there are no Stern's in my line. I know that the name of the town where my grandparents were from was changed by the Austrian-Hungarian occupation to Kakasalja at the time of their immigration.
Sorry I did not answer sooner but we have been on vacation.
