Thanks for getting back.
The Timms/Tymms with various other spellings were from Oxfordshire originally he was a stonemason. After the marriage the couple went on to have 8 children Thomas 04.02.1810 St Nicholas Asthall, William 12.07.1812, Richard 11.05.1816, James 13.06.1819, Elizabeth 17.11.1822, Clara 20.12.1825, Clam (male) 30.07.1826 and Mary 24.06.1829 all baptised at the Wesleyan Chapel Chipping Norton Oxfordshire.
With regards to the marriage there is only a transcription on FindMyPast and it's the same as the LDS
I found a family of Watkins from Aymestrey the father was Paul Watkins mother Sarah Evans. They had 7 children all baptised at Aymestrey but unfortunately not a daughter Elizabeth. This couple had also married at Aymestrey 22.03.1783.
Paul was one of the sons of Paul Watkins and Margarett Griffiths who was born at Lingen (6 miles from Aymestrey). There were 4 boys Paul 03.11.1745, John 28.12.1746, Walter 22.01.1748 and Humphrey 05.04.1751 all baptised at Lingen. Their parents married at Aymestrey 17.12.1744
Don't know if one of the other sons could be Elizabeth's parents. John I think married Mary Pope at Lingen 18.05.1782
The name Watkins seems prolific in Herefordshire though so very difficult to find the correct branch
Thanks again
Eileen
