Yes we are from the same family! Your Great Grandmother Pauline Leibowitz was a sister to my Grandmother(Fannie Goldstein Murray). I was in contact at one time with one of Eva Sigman's granddaughters. Sorry about Eva. I have quite a bit of the family history and would love to share it with you. I live in a suburb of Kansas City. Married and have three sons. How about you?
