My grandfather Irvin Conrad Maisel (Married to Ruth) died in 1933 two weeks prior to my father William I. Maisel's birth.
Irvin's brother was Arthur Maisel and he was related to a Conrad Frederick Maisel (Married to Maria).
I am not sure if Conrad Frederick was Irvin's father or brother.... but having been raised thinking my sons, brother, father and I were the last of the "Maisels" it was interesting to see your message.
My father was born in Michigan as was I. If you have additional info to share I would appreciate it!
