Alexisa's daughter was
Marie Poskrobko nee Kotowich
Marie's daughter was
Jadwiga Eliashuk (b 1900) nee Poskrobko
Jadwiga was born in Walchowycze. Not sure where that is though. I beleive she was married in Warsaw(1922). Her husband Jakim Eliashuk is originally from Berezowka, claimed Russia as homeland, then converted it to Poland. Berezowka is beleived to be outside Brest (Belraus) on Poland land.
Beleive proper spelling of last names to be
poskrobko, kotowicz and laszuk
