St Oliver Plunkett grew up in Loughcrew. Born in 1625, his parents were John Plunkett and Thomasina Dillon.
The following coat of arms is on the building at Loughcrew. It is the quartered arms of Naper and Gerard impaling those of Petty.
Sir Nathaniel Naper of More Critchell was knighted in 1617 by James I. He married Elizabeth Gerard of Hide. Their fourth son, James Naper married the niece of Sir William Petty who granted Loughcrew to the Napers. Naper: Argent a saltire engrailed between four roses gules
Petty: Ermine on a bend azure a magnetic needle proper at the pole star or
Gerard (Hide): Azure a lion rampant or crowned or a bordure ermine.
Can anyone identify or suggest the family for this coat of arms at Oldcastle.
