Rosalyn Rappel is a match in AncestryDNA to my wife, 204cM shared with longest segment of 52cM, which looks like a significant match.
If she is related we hope to find a new branch to the family, who lost many in the Holocaust.
Unfortunately there is no reply from her to my messages via Ancestry messaging system.
Searching this name in the internet I found only one possible person name Rosalyn Rappel, in New York, but she is either in her 90s or deceased.
Possible other member of the family in the same address is William Rappel.
We appreciate any help in contacting Rosalyn or any of her family members.
