I'm trying to find information about part of my family tree with a surname of HEYMAN (or with close spelling). The parents of my grandmother were Regina Heyman and Leon Wiewiorka. Leon had 6 siblings named Emma,Henryk,Dora/Dwojra,Jozef,Kuba and Zigmund. Their parents were Maurice (Moshe?) Heyman and Florentina Neuding. They all lived in Warsaw,Poland.
