This profile, Isadore Levitan = Isadore Levitan
currently shows Birth: October 12, 1891-- in Minsk, Minsk Region, Belarus
I believe this is Wrong.
There is a WWI Draft Registration for
Isidore Levitan -- living in NY - born 18 Dec 1892 in Minsk, Russia - filed in 1917, he is married with a wife and child
And one for
Isidore Levitan -- living in NY - born 15 Sep 1892 in Salat Kovna Russia - filed in June 1917, he is single
The second Isidore Levitan is living at the same address as is given for a Leo Levitan who filed in 1918 and gave as his nearest relative his brother, Alex Levitan. That is the Isadore Levitan that has the parents and siblings currently shown for this profile.
