I have not found this Suisdek name yet. Intriguing
Not even in the Lemko variats.
I am replying to Helon and Fal which are very familar to me.
I have not found proper contact information yet to call to Poland. Nor have I found out if Owsiany was Greek or Catholic Parish. I think Catholic, but not sure.
Yep I tried to contact throgh DNA study.
Have you had luck contacting relatives?
