Hi John, Have you the details of father for Henry listed on the marriage certificate, I have a feeling that the family I found in 1851 Brecon with Grandfather David and Grandmother Kezia is yours. I also found them in 1841 still living on the same farm which was named Cornwall which Jeff mentioned, this was before Henry was born. 1841 CENSUS David Pritchard Head age 50 Kezia Pritchard Wife age 45 David Pritchard Son age 20 (Possible father of Henry) Elizabeth Pritchard Daur age 15 Richard Pritchard Son age 15 Kezia Pritchard Daur age 10 Ann Pritchard Daur age 10 William Pritchard Son age 8 James Pritchard Son age 6 All born in County of Brecon. The ages on this Census was not always correct as you can see some were listed as same age but not twins, the enumerator rounded children's ages down by as much as 5 years. On the 1851 Census David junior was not living with family so could have been married and both the children Henry and Mary listed on the 1851 Census were staying with the grandparents at the farm. The only children listed in 1841 still at home in 1851 was Elizabeth, Richard, Anne, and James. If you obtain the marriage certificate and fathers name is David you have the correct family, but with Mary Hayes that will not be so easy to locate her records because of her being born in a different Country.
