I come from a Kenna family in Douglas on the Isle of Man.
My father is James Duncan born in Philadelphia, my grandfather, who emigrated to the US in 1920's, is John Leonard, and his father and mother are James and MaryAnn(e).
I am told that John Leonard had two brothers, one killed in a WW, Duncan, and another who emigrated to Australia, and one sister Gwendolyn who married a Stephenson.
Gwendolyn lived in Douglas, owned a hotel named Ballybeg, and had a daughter named Doris.
My father, youngest brother, and I live in Texas. I have a sister in Colorado and another younger brother in Florida.
I do not know if we are any relation, but I thought I would share...
