My estranged dad and his paternal granddad, Anthony John Czarnecki, Sr..
Born Antoni Jan Julianowicz Chernetski, Great-Granddad was the only Poland Russia-born son of Julian Jan Feliks Antoniowicz and Aleksjondria Alicja Antoniowicza Andrulewicza Chernetski. Both of his parents had parents named Antoni and Katarzyna; Julian's mother being Katarzyna Danilowicza Chernetska of the Krasne, Poland Danilowiczes, and Alexandria (nee Aleksjondria)'s mother being Katarzyna Margiewicza Andrulewicza. Meanwhile, Antoni Chernetski owned a family farm in Lipsk nad Biebrza (his son's and namesake grandson's birthplace); and Antoni Andrulewicz was also Antony Andrulevich, of the Andruleviches of Buzhanka in the Kiev region of the Ukraine.
As a Crypto-Jewish Roman Catholic in Sugar Notch, Pennsylvania with Crypto-Jewish parents who brought him there to escape the pogroms and resignedly assimilate amongst the no-better Anti Semitism and rejection by the Jewish community in America; Great-Granddad carried a bitter attitude partly because of his pogrom-escapee and Anusi existence.
My dad was, from an early age, a victim of this attitude; hence "Doesn't seem too upset at his [Grandfather Czarnecki]." Meanwhile, my dad obviously cut the last part of the caption in the photo while scanning the photo, which I had to figuratively twist his arm to get. Like grandpa, like grandson- and ironically, the grandson who he didn't want to be; the one like his Pop-Pop Czarnecki.
