I have traced family back to Clondavaddog, Fanad, Donegal who may be related to your Friel family. I have not been able to make a connection, but on the Baptism Records for the children of my great-great grandparents, they have sponsors with the last name of Friel. I don't know if the Kerr's and/or Gallagher's were related to the Friel's, but it is common that a close relative would be a sponsor.
My G-G-Grandparents were Charles Kerr/Carr b.~1832 and Grace Gallagher b.~1833.
Their children's names (and sponsor's listed on Baptism Record) are:
Daniel (Bridget Friel and Edward McGrenaghan)
Mary (same as Daniel's)
Catherine (Hugh Friel and Sarah McConigley)
John (John Friel and Mary Gallagher)
Edward (Mary Gallagher and James Kerr)
Sarah (Dennis McConigley and Mary Kerr)
Maybe we have a connection?
Have a great day,
