I have a Rody Ahern and a Mary Dwyer listed on my great aunt's baptism records from this area.
We have documents that spell name: Ahearn, Ahern, and Aherne
Rody Ahern and Mary Dwyer were the sponsors of Julia Agnes Ryan's baptism in 1885.
Parents were Patrick Ryan and Margaret Aherne married Feb 1872. Patrick listed as from Caherne and Margaret from Glenough.
They had several children: John, James, Mary, Margaret, Bridget.
They came to Brooklyn, New York in 1890.
Patrick had 2 brothers we do not know the name of; one went to Australia and one went to Chicago.
Margaret Aherne's parents were John Aherne and Margaret Heffernan.
Any connections?
