In researching the below question on Louise Henry I decided to type in Marc Lawrence to see if he'd show up.

Sure enough, he did (please see link). The SS record shows him with a different birthdate (December 17, 1909) which is exactly 2 months earlier than his official bio of February 17, 1910.

The date of death is off by one day also but the location is the same.

Totally meaningless info but interesting trivia nonetheless.
