Sue Hall, there are a few private Facebook groups dealing with the DNA of the Polish/Ukrainian area. There are several groups attached to cultural areas, although the only DNA projects are Lemko Ancestry and DNA, and Our Ukrainian DNA. They are found in the Ancestor Projects section at GEDmatch.com.
My experience (not reading Ukrainian, Polish, or Russian) with this is that the research is difficult--using church records, mostly (many of the records are in Latin, however). The Lemko DNA project is for the one specific geographic area of Galicia (from which area my grandparents came). I am actively doing research with the Greek Orthodox catholic records, but I can't yet handle a specific One-Place Study. I would like to eventually do such a study for "Ustrzyki Dolne" region in (now) SE Poland.
