Hello , my grandmother, Eleanor Peet Fisher's family came to Youghal and with the line you mention. Her mother, Sarah Wright, married Abraham Fisher, whose brother was Reuben Fisher of the family coming to Youghal. The Wrights also came from England to Ireland about the same time as the Fishers. They became Quakers in Ireland. I do not believe they were of such in England.
My gr grandfather, the youngest sibling, left for South America with his family in the late 1800's. The family business in Youghal was to my knowledge on tender hooks.
He sent a telegram to his wife Sarah, not to bring the family to Argentina, as it was not a place for their many children... Sarah never got the telegram and brought all their family to be with him at the British Colony, Argentina.
From there after some years they went to North Carolina, and thence to Pennsylvania, although not with Sarah, she had returned to Cork and died there.
My cousin Rebecca Fisher is trying to get in touch with you. ( Philadelphia) . She has all the family records in front of her at all times. Margaret Brinton Collinson
