Re: Medieval Saxon migration to Ruthenia (Ukraine)

I'm working up my genealogy, my family is originally from the eastern side
of the Carpathians in Ukraine, specifically the foothills - Sambir region.
Their clan name is Sas (Saxon in Polish and Ukrainian) and are descendants
of one group of Saxons led by comites Huyd in 1236 (from King Andrew II of
Hungary's court) to assist the Ruthenian King Danylo.
Would anyone have any information on that offshoot or at least could
direct me to other references?

Would appreciate any help.
