Neville (Nevil) Family from Ferns, Wexford

I have been researching my Neville family, originally from Diocese of Ferns, County Wexford, for many years.  I have been able to locate James Neville b 19 Oct 1775 and his wife Catherine Crane, b. 1780 in Wexford and trace the family up to the present.

I would like information regarding the family before 1775.  I believe James's parents are Edward Nevil b 1749 and Catharine Lamport b 1749 both from Ferns, Wexford.  I also believe Catharine's parents are Patrick Lamport b. 1707 in Ferns, and Catharine Sinnnot. I am not sure if this info is correct.

Can anyone give me any further information?
