Murphy! (The most recently arrived of my Irish ancestors… in the 1870s we think)
Conn, Porter. Downpatrick, County Down. Arrived in the 1850s.
McConnell. County Down? Arrived in the early 1700s.
Granville. The one who immigrated to the United States in the 1850s was born in Wales… and of course the name originates in French/Norman lands. As far as we know he was Irish, though he died when his children were young so their stories (now retold over 100 years) might have been misleading.
Other family names from Celtic lands: Duncan, Glenn, Livingstone(?), Watson (?)
None of these people came as a direct result of the potato famine — the last four names came for religious reasons (Puritans) in the 1600s but were from Scotland by birth.
