Thanks so much for your feedback. I knew some of this. Jeremiah Hayes married a 2nd time and on that record and his death record, he father is mentioned as Francis. There is also a Thomas Hayes who farmed Tonerevan, so I assume he took over from Francis and is Jeremiah's brother. Tonerevan or Tonyrevan is very close to Breandrum and Carn, farmed by Jeremiah. Jeremiah had a daughter Mary Anne Hayes who married a William Darling who was a farmer in the district. I assume he was her cousin (her mother being Esther Darling). Thanks again.
