Hello Adrienne, I have a minor interest in the late 17th & early 18th Century K.Patrick Kelly's.
A family living in Balladda, Dalby were neighbours of my lateral family - Kermod.
The K.Pat; B.R. records the burial of a William Kelly in 1741/2. He left a will. This will and the1749 will of a Thomas Kelly of K.Pat are on Brian Lawsons' BMD Site.
If you can access them (I can't) and you find that are your ancestors and they lived in Balladda - I can give you some info about the family from C.1670 -1750.
