Dear Tracey,
I think this is the same extended family. Henry O'Flaherty who married Elizabeth Biesty, had six children: Anne Mary, Henry Patrick, Elizabeth, Margaret, Kate Deale and john Joseph. Henry's parents were Patrick O'Flaherty and Mary Riely. Henry was born in 1851 and did not emigrate, nor did his wife. She died in the U.S. visiting her daughter Annie. According to another Manion, these O'Flaherty's were from Patten Park in Ballyhaunis.
