If you have truly written the above letter, you would be lying if you said no more relatives to find information from.
What you need to say is you have elected to not speak with me, your sister anymore, ALL YOUR CHOICE. YES, RAPPAPORT WAS I BELIEVE OUR DADS MOM;S LAST NAME. OUR UNCLE AVROHAM RAPPAPORT, WHO LIVEED IN NYC THEN MOVED TO ISRAEL, ALSO OUR AUNT EVA WHO LIVED IN NY TILL HER DEATH.
AS YOU CAN SEE I DO HAVE SOME INFORMATION BUT AM TRYING TO FIND RELATIVES IN CALIFORNIA, WITH ORIGIN FROM AUSTRIA THEN CZECHESLOVAKIA IN EUROPE.
POSSIBLY AS OUR DAD'S ORIGIN WAS WITH HIS FAMILY ORIGINALLY.
