In researching my grandmothers family which is Sughrue I have come across info on the name Flahive. My grandmother Helen (Ellen)Sughrue was a sister to Julia Sughrue b. about 1877 Droum Glenbeigh, Kerry. She married a Patrick Flahive on April 15, 1900, not sure whether in USA or Ireland. They may have settled in Boston area. Patrick was the son of Thomas Flahive and Jane Sayers, Ballynane, Annascaul. Hope this info is helpful.
