Hello Janet, I'm not sure we have a match, as some of my info is sketchy, but I have a Dennis McSweeney, D.O.B. ?/?/?
from County Longford, Ireland(St. Helens, Lancashire?) moved to the U.S.(NYC, eventually settling in New Rochelle) around the turn of the century - his wife's name was Ellen Coughlin I believe, though, and I have info for 7 kids, some of them with sketchy info, but 3 with birth years 1903, 1908, and 1915.
I know Ellen's last name doesn't match your post, but I thought the rest was close enough to mention.
