Sorry to sneak in on your posting as I am afraid I cannot help regarding Richard Miles. But in case other Miles reearchers are reading your post, I have tried unsuccessfully to trace a Mary Miles born about 1751, for whom I had thought there might be a Monmouth connection.

Mary Miles married my 4 times Great Uncle Richard Marfell in Hope Mansell 27 May 1784. Richard Marfell & Mary nee Miles farmed at Trostrey near Bettws Newydd. Mary died 23 January 1844 in Trostrey. There is a difference between the death certificate, which shows the date as 23 January and the Grave Memorial : "Sacred to the memory of Richard MARFELL of this place who died March 31st 1843 aged 86 years, also his wife who died Jan 26th 1844 aged 93, also in memory of Timothy their grandson who died July 10th 1876 aged 52."
