From this information once again thank you :)
I have now found out that Thomas Evans Parents were Morgan and Kath ( Catherine, Katherine) Evans, Siblings were Morgan junior and Mary.
Thomas was at some stage in the 75th regiment for 4 years. not sure on the dates though..
speculation is that after Thomas left the regiment he may have moved to Llandrillo yn Rhos.
Thomas married Anne Hughes march 1847 (Anne parents are John and Mary Hughes).
in 1851 Census Anne is with one Child Catherine Evans 5 years old, i found a birth record for Catherine as parents being Thomas Evans and Jane Williams. so im thinking that Jane may have been the wife that died and Thomas may have married Anne so Catherine had a mother figure in her life. since he was in so much trouble with the law...
why i say this is in another piece of information i came across Thomas has likely taken the whole blame instead of dobbing in his father in law.
so know im hoping that some one may help me find the marriage information for Thomas Evans and Anne Hughes in march 1847.
