This summer I came across a family tree that was researched through extensive letter writing in the mid-1900s. Enoch R.L. Jones and his cousin Chester sent a copy of their work as of 1941 to my ggrandmother, Irma Jane Jones. This tree starts with Daniel Jones Sr, b. 1725.
Subsequent to this Enoch found a photo that appears to link Daniel to Thomas Jones, Welsh Quaker, who emigrated to the America in 1683. I believe his father was John ap Thomas. I have not as yet, been able to establish the link between Thomas and Daniel, although I suspect that it is Thomas's son, Evan.
I would be glad to share any info from this tree if it will be of any help. There are some side branches of this tree that go back quite a ways such as, MERRILL
