I discovered that a Morgan Flaherty left Ireland on the Carmania from Queenstown (Cobh), on Feb. 20th 1921. He gave his home address as Ballygarron, Spa, Ireland. (The) Spa is about 4 miles outside Tralee on the road to Fenit.
Morgan (50) was accompanied by his wife Hannah (45), John aged 15, Eileen aged 9, Eugene aged 8, Bernard aged 5 and Cicelia aged 2.
They were bound for the home of their son Morgan who was living at 51 Bellew Ave., Haverhill, Massachusetts.
Morgan Senior names his father as John Flaherty, Ballygarron, (the) Spa, Tralee.
When I checked the RC Church records, I found Morgan son of Morgan Flaherty and Hannah Heffernan born on July 1st, 1889 at Baltygaron, the Spa.
The US Census 1930 finds Morgan (59) and his wife Hannah (55) living at 205 Seventh Avenue, Haverhill, Mass. with their son Eugene (21) daughter Cecilia (17) and grandson Daniel B. Sullivan (2) Their grandson Daniel is listed as born in New York of parents born in Ireland.
Michael Flaherty, his wife Helena and their children live next door. Michael and Helena were born in Mas. but both their parents were born in Ireland .
