Ley S of Cornwall 1700 S

I am looking for more information on Richard Ley, who married Mary Jane on Dec 07 1774 in St Cleer, Cornwall.

They had 3 children that I have been able to find records for:

Richard Ley b.March 13 1775 in St Cleer, Cornwall
Catherine Ley b. May 11 1777 in St Cleer (she is my ancestor)
John Ley b. Aug 1st 1779 in St Cleer

If anyone has any information regarding this branch of the family I would be very grateful to hear of it!

Many thanks,
Kirra
