WWII Netherlands Escape Lines 
My father was in the Merchant Marines during WWll and I am trying to find any info on him. He was born in 1897 in Rotterdam Zued Holland. He was on a merchant ship , name unknown, and he had a pass to travel over the waters during the war. If there is anything you can tell me or direct me to someone who might be able to, I would appreciate it. His name is Herman A. Scheepsma Thank you, William J. Scheepsma
