Joseph Ewen, New York or New Jersey

Hello, I am researching the Ewen family.My father John Ewen is now deceased.He had a brother Joseph.Joseph died probably back in the 1930's.Joseph cared for and raised my dad when his parents died.I would love to know anything about our extended family possibly back in New York or New Jersey.If anyone has any information please email.The only information I have is he had an Aunt Betty.Thanks
