Harold J. Hatton , 73, of Great Kills, a retired knitter mechanic, died Wednesday in Sisters of Charity Medical Center, St. Vincent's Campus, West Brighton. Born in Brooklyn, he moved to Great Kills in 1995.
<snip>
Surviving is his wife of 45 years, the former Katherine Kennedy; three daughters, Katherine Hatton , Teresa Fagan and Eileen Donohue; a sister, Helen Scott; a step-brother, Arthur Harning, and two grandsons.
This gives us the name of his wife and children. I found another article with this mention of Katherine and Teresa, which gives Teresa's town.
"Katherine Hatton , Great Kills , 'We had a small family gathering at my daughter's [Terry Fagan] home in Eltingville.' "
I can't find an obit for Katherine so she may still be alive...if not, there is a town for Teresa, so someone could perhaps track her down. She would be the half-niece of Arthur (assuming the census info above is for the right Arthur, and I believe it is).
