Terri, I think I may be your cousin. I do remember Uncle Irving having a daughter Terri who was younger than me, and we have home movies from my Uncle Wally's house where we were running after each other at a family party around 1961 or 1962.
My mom is Kathleen Kirschner Lubetkin, born 12/22/1921. Her brother was Irving. I have lots of family info, but not as much on the Kirschner side. Would love to hear from you. Call me at 856-751-6146 or email me.
I have his birthdate as 30 May 1916 in Danbury CT. If this is the right Irving, we definitely need to talk!
