Scanlon-Griffin of Spiddal-Rossaveal

Thanks to this website I was able to find my grandfather Peter Scanlon birth record 04-Jul 1874 and I believe I found all his brothers and sisters birthdates Delia (Bridget), Patrick,Mary, Catherine, James, Barbara & Maggie. Their parents were Patrick Scanlon & Mary Griffin. I know many of the children came to Portland ME and married including my grandfather who married Agnes McDonough (born 1877-78) in 1904. She was also from Rosssaveal. Thanks again I found her baptism record. Her parents were John McDonough and Bridget (Delia) Conley or Conneely). I think I found a record of Patrick Scanlon death in Ballintleva in the 1900 records at the age of 76. I'm trying to find the names of parents of Patrick Scanlon and wife Mary Griffin and the parents of John McDonough and wife Bridget Conley. Any kind of records available that may show the names? I know the possible birth years 1820-30s may not exist.

Thank you.
