My father was David Roy Dunham, born in Hornell, NY in 1896.
He was the son of Dr. Roy and Mary Linderman
Dunham. He had at least one brother, Richard,
and a sister Katherine. He moved to Clearwater, Florida
in the 1940's and died in 1961. I know he was married before
moving south and had some children from that marriage.
He was granted a divorce before marrying my mother in 1947.
I do not know if there is any connection with your family, but I doubt if there
were too many Dunham's in Hornell, NY.
I know my Uncle Richard became a well-respected Professor of
Theater at the University of Wyoming and University of Hawaii.
Can anyone provide additional information?
