"Martin Fullum had one daughter named Mary Ann Hannom (nee Fullum). Mary Ann married and had one daughter, my grandmother Bridget McAuley (nee Hannon)"
What is very interesting here is your father's age of 81 years. This is the longevity "Fulham gene" most male Fulham members have an average of 86 years, The female members live into their 90's. Irrespective of the spelling all Fulham members have the same DNA and family gifts.
Martin Fullam(etc) is a City of Dublin surname yet it was found in the 1800's in County Kildare when a Martin Fullam died in poverty. He was a Land Agent and he was attacked by local Fenians and crippled of course the landlord done nothing for him or his children.
It is also found in my family of 1800's County Longford that Martin was also employed as a Land Agent whether it is the same person I do not know as the above story is hearsay via a New York family member.
There is a family in New York City and New York State descended from the Martin Fullam of the City of Dublin Liberties 1849 (New York City) Their relatives are still found in the very same area where the NYC FAMILY LEFT IN 1849.
