During the 18th, 19th and part of 20th centuries when Russia, Austro-Hungary, Prussia divided Polish Commonwealth among their "ambitious" selves, they tried refer to my ancestors living south of Carpathian Mountains (Podkarpackie) as RUSYNS or RUTHENIANS. Here is some info on Rusyns.
" Their language, called Rusyn or Ruthenian, is a variety of East Slavic and is spoken in Lemko, Hutsul, Boyko/Bojkian, Sjan, and Transcarpathian/Verchovyna dialects.
Their traditional religions for centuries have been Eastern Orthodoxy and Greek Catholicism.
It's believed that the Rusyns descend from multiple old tribes including White Croats, Rus', and Vlachs.
It is interesting to add that according to some American documents from the beginning of 20th century there were about 100,000 immigrants to the US born around Kraków (Southern Poland) who declared themselves to be Bielo-Chorvats, i.e. White Croats by nationality."
Among Rusyn members of the "Carpatho-Rusyn Heritage DNA Project", these are among the Y-DNA haplogroups:
• E-L117 from some with ancestors from Slovakia and Ukraine,
• E-L142 from some with ancestors from Ukraine and Poland,
• E-L542 from some with ancestors from Ukraine, Poland, and Slovakia,
• I-M170 from some with ancestors from Ukraine and Slovakia,
• I-P37 from some with ancestors from Ukraine, Poland, and Slovakia,
• R-M198 from some with ancestors from Slovakia,
• R-M269 from some with ancestors from Slovakia and Poland,
• R-M512 from some with ancestors from Slovakia, Czechia, Poland, and Ukraine,
• R-Z283 from some with ancestors from Slovakia and Ukraine,
• R-SRY10831 from some with ancestors from Ukraine and Poland,
• and I-CTS10228, R-Z280, and several more.

My ancestors descended from Vlachs which is opposing Tomenable earlier statement that Poles do not descend from Vlachs. Also no R1B was found among these southern POLISH/ UKRAINIANS. Even some haplogroup E was found but definitely no R1B here.
