Referencing the Parish boundaries again; I see that the Will of Richard David of Strygosfawr comes under the Parish of Ystrad Meyric although, later, the farm comes within the Parish of Lledrod.
I'm always on the lookout for any link to RD of Strygos when reading other Wills. The Strygos Will is about as simple as it gets and mentions his wife and children. There are no other relatives shown to give us a clue as to who his parents were or how old he was at death.
Using the average age for marriage as 35 we see that his eldest son, David of Ffos, marries Letticia in 1735 giving his estimated DOB as C1700. Richard David, marrying at 1700 would have an estimated DOB of 1665. The problem is that the Wills that we have been reading, although showing a few Richard Davids as relatives, don't indicate their ages.
We could be looking straight at the correct family, without knowing it; nephews, sons and cousins could be of any age.
The same too for David and Goley's forebears. He married C1698 which places him at the same Circa DOB as RD of Strygos. Thomas Richards, (Edward Richard, Schoolmaster's father), would also be of the same approximate DOB.
There is an indication showing that particular families tended to stay in the same area and I would tend towards Lledrod as being the source of my family line. I'll have another read of the Will of David Richard of Bronwenllwyd, dated 1668. (within the cluster of family in Lledrod), to see whether I've missed anything.
Regards, Peter.
