I am looking for any information, or suggestions on where to look for information regarding the Maye's from Croghan.

My Gran Was Teresa Maye (1922-1987) she married Gerrard Alphonsus Kelly (1915-1983) from Elphin.
Her Father was Thomas Maye (1878-1947) and Mother Mary Anne McGovern.
His Father was Patrick Maye (1839-1883 and Mother Honora Beirne.
His Father was Cormac (or Thomas) Maye (1800-1863)
His Father Was John Maye (1760-1818)
His Father was Dennis Maye (1730-1830)
All of the male line names and dates came from a family bible long since lost.

How can i go about confirming any of the above details? All help appreciated!
