thank you for all your help, It looks like there are 3 Levi Thomas of approx same age. 1 the Baptist Minister and 2 others Labourers. my G Grandfather , Benjamins birth cert states that his father Levi was a Agricultural Labourer.
(Ben was born at Hamlet of St Martins Haverfordwest in 1852. ) so I think my Levi is either the one born in Wigbowell (maybe this is St Dogwells) or the one born in LLanychare. With the info you have given me I will try to put the jigsaw together.
Do you know if the Welsh named their children like the English, 1st son after fathers father, 2nd son after mothers father,1st daughter after mothers mother , 2nd daug after fathers mother.
