Looking for any information/meanings on the surnames Patac and Olgrtis. The latter may be spelled incorrectly, as it came from the return address on an old letter. It was from Rusocice, Czernichow, Krakow. Valenty Patac was listed as a border in my grandparents home on the 1920 census. This spelling may or may not be correct. My grandmothers name was listed as Mattie, yet another interesting way to pronounce and spell Mary. TIA Dennise
