He was living at 2421 N. 31st Street in Philadelphia. Although he claims his age as 19, he was not yet 17, based on his date of birth of November 10, 1900. He was working as a Machinist for the government at the Navy Yard in Philadelphia.
The reason I know this is Rose's oldest brother is that he lists his nearest relative as his father, Max Levitt, living in Woodbine, Cape May County, New Jersey.
Uncle George was of medium height and build with brown eyes and black hair. He registered on September 12, 1918 in Philadelphia.
I wonder what made him decide to move out of his home in small Woodbine, New Jersey, to the big city before he was even eighteen years old?
