erndeb: There was a William Thomas Davies born flint approx 1866 (not in my family so far as I know) you can find him on 1861 census RG10/5644/57/9 at 58 Sidney St , Flint. 'William Thos' was aged 5 and was the son of William aged 34 a Chemical Labourer born in Mold. Wife Anne aged 35 born in Flint as were all the brothers and sisters of Williama thomas:Mary Elizabeth, 11; Samuel 3; Ellen 1; Martha Ann 9. The only way to be sure if this is your William thomas would be to look for his birth in GRO and get a birth cert.
