Re: Not much to go on
As far as I know, my grandfather - Stefan Balko (b. December 11. 1913) - origignated from Polo-Ukrainian family of Balkos living in Mosty Wielkie (Mosty Velyki) near Lwow (that's the Polish name of the city, Russian name: L'viv, German name: Lemberg). His father's name was Jan (John) and his mother was Apolonia Harysa. Jan had two siblings: a brother Emil and a sister named Emilia. Jan's mother's name was Aniela.
Unfortunately that is all I know at the moment.
Hope this will help.
I would be very grateful for any information about Balkos from Mosty Wielkie since all of the name bearers must have been related to my ancestors one way or the other.
