Thank Osprey (again).
New line of Rees family just uncovered, that is, Martha Rees the wife of Timothy Powell. Her Will of 1822 recorded her brothers as being my ancestor David Rees of Westfields and John Rees of Westbury Hill, and a yet to discover grand daughter Sarah Gutridge.
David Rees at Westfields in 1822 is a mystery to us; therefore, we have just prepared land tax records from 1788 to help uncover this mystery. This David Rees was at Castle Inn, Haverfordwest until Jul 1805 (The Cambrian); Derby farm St. Issels Haroldstone; 1817 Woodbine Cottage, so our first thought was the Westfields farm adjacent Woodbine Cottage and Derby farms in 1822, before moving on to Dredgman's Hill 1831 (Will); then back to Derby farm and Green Hill farms by his death in 1837. All farms very close to each other.
There were two other Westfields farms , west and east of Rosemarket, and two John Rees' occupied them. It now throws into the equation that maybe David Rees' uncle was also called John Rees, and he may have leased West Hill; Westfields on the east side of Rosemarket.
Brother John Rees also connected to both Westfields near Rosemarket.
Thank you for the Powell information. I will need to thoroughly research Mary Powell's husband Griffith Evans. In 1831 Will, David Rees' sister also called Sarah Evans. I can't find her death bp. 1757 Freystrop and expected death between Will's of 1831 (beneficiary) and 1835 (not mentioned).
