Rachel Kaluszyner - kaluszyner

I am looking for any relation to my great grandmother Ruchla / Rachel Kaluszyner. she was part of the resistance and dies in 1942. her husbands name was Harry / Henoch Spiegel / Szpigiel. She was one of about 14 children so I figured that someone had to get out and away from the war. My grandmother has not seen her mother since she was 12 years old. we are having a hard time finding anything on her even pre war. Her two children that she has are named Odette Spiegel and Michel Spiegel. Please, if anyone can help, I want to solve a 75 year old mystery to be able to give my grandma some peace before she too passes.
