john kenny born 1927 NYC, NY sibling of Michael and Patrick Kenny of Irle

I am looking for family members of John Kenny (born 4/15/1927). He had two brothers Michael and Patrick Kenny. He also had a half brother James Hughes (was a catholic priest) and he had a sister. I think her name was Margaret. All his siblings were born in Ireland, but John Kenny was born in NYC, NY. His parents were Michael and Brigid Kenny. He married Alice Lawton in St. Albans, Vermont in 1955 (?). Any information would be greatly appreciated.
