Good afternoon Amy
It has been some time since I got involved in family history, am now working and living in Asia.
I have started to be interested in John James Maund as I now have many copies of parish entries for wales, but reading the letters of John James Maund who you indicate was born in 1765 and his father dies in 1799 at the age of 99, it would make his father about 65 when John was born!!! or he married late and had a very younger wife or he married twice again with a younger wife.
I cannot find any Maund who dies in 1799 at the age of 99, may I know where the information comes from that he was born & from Wales? do you know the ship that he arrived on from England and where it left port?, what was the name of his daughter that came back to England after his father's death, did he come with her and if so what was the name of the ship, the port it left and the intended port in England?
Sorry it has taken so long to get back to you..
Warm regards Gary
