Hi,
I dont know how much help I can be, but we may be able to help each other, perhaps.
I have John HOLYMAN who married Mary FINNIS in 1775 in Deal KENT.
At marriage, Mary was a minor, and daughter of Wm F.
There was a William FINNIS who may have been her father, who was buried 7 Apr 1829, at Buckland, aged 77.
John and Mary HOLYMAN had a least one child, William, who married Sarah GREENWAY, but died in 1827.
Sarah's second marriage was to John DOLBEY, in Dover, KENT.
John and Sarah DOLBEY emigrated to Tasmania, Australia, in 1836.
I am descended from this couple.
I hope this is of help and interest to you.
Love to know anything more.
