Hello Bryant
Birth certs first:-

Father's Occupation Pig Dealer. Informant Mary Batham Notting Dale Kensington , mother of child.

Death Cert

Census 1851
Parish Kensington Address 131 Potteries or Notting Dale.
William BATHAM Head 66 Journeyman whitesmith born St Martins
Mary '' '' Wife 56 '' St Giles
George '' '' Son 12 Assistant '' Kensington
Edward '' '' Son ? '' '' '' '' ''
On my copy Edward's age is hard to read.
On marriage Cert of Edward to Mary Harrington in 1858 his father is shown as Christopher William Batham Locksmith and Bellhanger.
On marriage Cert of Louisa Batham in 1854 resident in Potteries her father is shown as William Christopher deceased.
Kensington....Potteries and Notting Dale are the same place.
For what it's worth , in the Westminster Polltax returns for 1796, a William Batham Locksmith of Peter Street is listed. This is probably in the right area for St Giles and St Martins origins of my William and Mary.
