Hi Doris
I think I have some info. My grandfather was Michal (Michael) Iskra their were 8 siblings:
4 boys : Michal, Peter and two who I do not know the names. The 4 sisters are: Marja (Mary), Eva, Frania (Frances) and Catherine (Kasha or a/k/a Katarzna)
Michael stayed In Poland and married Karolina. They had 7 children (2 boys died in infancy) Their children are: Jozef, Hania, Joanna (aka Grazyna), Stasia and Wladyslawa (Wladzia) (MY Mother).
Peter Moved to France and had 4 children: Janine, Frances, Ania and Peter Jr. I believe
Marja (Mary) has a daughter Anna April with her 1st marriage. Her daughter stayed in Poland with her 1st husband when she moved to the United States. She remarried and had two more children, I believe their names are Anthony and Felecia.
Frances moved to the US I know she lived in Clifton and she had 1 daughter, Genovefa Grembowiec.
Eva also moved to US and she had one son, Edward Sopczak
Catherine (Kasia) had 4 childrenl. Sophie, Stasia, Stanley and Jozef.
I know that Catherine's daughter Sophie married and her last name is Bialas. I'm sure I could get more Info regarding from my mother. My mother and Sophie are 1st cousins. Hope this helps.
Sincerely,
Elizabeth
