I do not know if this is any help, but my gg grandmother was Mary Power(s). I do not know where she was born (other than Ireland) but her husband gave Tralee as his birthplace on his US citizenship papers. She had a brother, Nicholas, who gave Mitcheltown as his birthplace on his papers. She also appears to have a sister Johanna (m. Timothy Cronin). Her parents were Roger & Hanora (Anna) Cane. Mary married James Roche in Haverhill, Massachusetts in 1857. The other 2 also came to Haverhill & so did their mother (I cannot find any record of the father). Nicholas became the first Irish Catholic undertaker in Haverhill.

If you think there could be any connection, I would love to hear from you.
