I have a similar story to yours. My grandfather was also in The German Merchant Marine shipping out of Hamburg. He visited this country several times on German merchant ships and liked it so he brought his wife and 4 children to NYC in 1911 and settled in Brooklyn working as a cabinetmaker. I've tried to find a source of information/records of the German Merchant Marine on the internet to find out what Line he worked for and ships he worked on but with no luck. Do you by chance have any information on where such records might be located. Thank you.
