My husband's grandmother was born 6 April 1901, St. Petersburg. She was baptized 40 years later in Kassel, Germany in refugee camp: Vilhelmina, daughter of Adomas Kisel-Kisko and Liucija Maniusevskaite (which is a Lithuanian name). Vilhelmina says Adomas died in the St. Petersburg baths when Vilhelmina was 4, leaving her, her two younger sisters (Malia and Bronislava), and Liucija alone.
We believe that Liucija subsequently remarried, possibly to a Kuzmimas, as a family photo shows Malia, Bronislava and her son Stasuke at a gravestone labeled Liucija Kuzmimie... (the rest was obscued with flowers). On the back in Malia's handwriting is written "our mother's grave".
Vilhelmina never wanted to talk about her background, so we don't know much more. We've wondered if there is a Jewish connection. Any info on how to find a birth certificate in St. Petersburg, or on the family itself would be much appreciated.
