Hello Pauline - I found Mary Banks on the 1861 census at Brun Coch Berwick. She gave her birth place as Durham. Father William Banks aged 55 from Llandilo Talybont and mother Mary aged 48. with other children. No place of birth for Mary. I then looked at the marriages on the cd and found a William Banks marrying an Ann Williams in Llanelli 27/5/1835. It is the only Banks on the marriages that I cound around the right time. Could you have a look at that marriage to see if it gives a church please. Have you struck gold I ask myself! I could not find the family in 1871. best wishes diana
