The only connection to Driscoll is my 3rd GGrandmother, always referred to as Helen in family stories, but I believe it to be Ellen. I found a William Mahan, my 3rd Great Grandfather in Cazanovia, New York in the 1840 census with wife, son about 12 and daughter near 5 years. Later documents show an Ellen Mahan in Cazenovia, Wm had an article in the Republican newspaper stating his death in March 1849 by drowning in the pond by the mill. I have tried to find a Helen/Ellen Driscoll Mahan for many years. Both Wm and Hellen/Ellen were born in Ireland and stories say they came to America at a very young age; both said to have died in New York State. I do not have a William Driscoll that I am aware of in the files.
