ALBERT LUNA ANDERSEN

Hello All, Just joined up and take pity if I don't follow the right format. I'm sure someone will tell me. Found my Mothers family now I'm trying to find my Fathers, No family information except his name and a marriage date of 1932 in New York City, USA. Was told he was a Border Guard on the Canada, US border, then a truck driver and then worked in Bethlehem Steel in Staten Island N.Y. WW 2. e was friendly with a family named "Knudsen" Where do I go from this tiny bit of info.? DEL
