My maternal grandfather was Harry Flum. When my mother's older brother went to school the teacher added an 'a.' The name became Flaum. Grandfather Harry came from Gostynin, Poland. He was one of nine brothers and sisters.
His parents were Yehuda Laebe and Basha Sureh Flumenbaum. I found his entry from www.ellisislandrecords.org as Harry Flambaum. I am still looking for his social security application (freedom of information act) that would help to shed light on his actual birthdate,etc.
Is any of this information helpful to you?
Please let me know.
Thanks,
Richard Cohen
