Hi - are you sure the village is Bobrowiki and not BOROWIKI ....?? Are we talking about the Braslaw area? Pietkuns are prolific there.
I've been tracing an Apolonia Skurjat who went to Argentina in 1927. Her maiden name was Pietkun and she came, I believe, from Jodlowicze, Opsa gmina but which is closer to Braslaw township than Opsa. But the village of Jodlowicze is where she spent her early marriage years with two small children. She declared on documentation that she was from Wilno, Poland - which of course was correct but non-specific. Her documentation also stated that her parents were Kazimierz Pietkun and Kazimiera Puszko. Apolonia was born 10.2.1905.
Apolonia was married to Adolf Skurjat of Jodlowicze, born 1899.
Looking through the incomplete Braslaw RC church records, I can't find a Puszko (although there are two Puszkos in the 2003 Braslaw phone book). I thought perhaps, due to often poor transliteration between the languages used in the records, and the differing suffixes, that perhaps Puszko was Puisza. Dont know.
There were several Pietkun groups in Borowiki and other lots in Rozowo, Ozerawace and Jodlowicze, Pietkuniszki etc etc.
My Pietkuns are:
Michal Pietkun + Petronella Glinska married circa 1877 - of Borowiki
who had:
Adam P born 1878 married Helena Andreeva
Michal P born 1885 (my line) married Adela Wabel
Wladyslawa born 1886 married Michal Puisza
Albina born 1890 married Mikolai Sielicki
The Pietkun christian names were re-used and re-used - it's enough to drive you crazy. I have an Iganacy Pietkun from Borowiki, also an Anna and Elzbieta, but not a Stanislawa that I know of.
My area of interest is Braslaw, Opsa, Widze, the parish of Smolwy ( Zasalacie, Zatokai, Czepulkiszki), Turmont, Lithuania, Dvinsk/Daugavpils
Researching: Pietkun, Skurjat, Labonarski, Umbras, Raginski/a, Valackas, Survilo, Gulbinski/a,Wabel, Bosak/Bacak, Samsonowicz, Bogdanowicz, Lapinski, Slawinski, Luck, Bals etc etc
