I think that we share this descent from the Quayles of Glen Maye or Glen Rushen?
I made some notes on the Patrick Quayles some years ago, and I noted that the Thomas who died around 1678/9 (of Ballamoar) had younger sons Thomas Henry and Robert. Henry was left £15 by his father, to be raised out of the estate.I am not guaranteeing this is our chap, but at the time I thought it possible.
Cheers
