I think there has been a mix up in family trees for this John Lewis b Gloucestershire c1844. A number of trees have my family connected, but as far as my research there is no Gloucestershire connection.
Ebenezer Lewis 1782 - 1847 is my 4th great grandfather (DNA verification)
Daniel Lewis c1812 - d bef 1871 is brother to my 3rd great grandmother Mary Lewis b 1830 Ystradgynlais, Breconshire.
Daniel did have a son John bc 1842/3 Ystradgynlais, his mother from census was Elizabeth, nee Williams from marriage in 1832 and children's GRO birth reg. John still in Ystradgynlais with widowed mother, unmarried in 1871.
Interestingly I have many DNA connections for Grundy decendants through her mother...Mary Lloyd. My 2nd great grandmother was Jane, sister to Mary, daughters of Thomas. Jane was the only one that stayed in Wales when they up sticks and moved to Tasmania in 1855.
