I'm an English Porterfield who's grandmother was an Donegal Porterfield.I have good recent history (family reminiscence, 1912 Ulster Covenant) and good well known old porterfield history.I would love to connect myself to the Scottish Lairds but I have a bit missing in between. Does anyone know if any of William and Isobel's children / grand children remained in Ireland and did not emigrate to USA? If so I would be their descendant. Can it be shown that the whole family moved to America, if so, how come I have porterfield relatives in Donegal as recently as 1905?Can anyone help? Thank you very much in advance!
