There is only one David Walker bc.1792 Suffolk, and that is one bp.12/1/1792 Sudbury (not sure if it was Sudbury or not as one finds a lot of baptisms that supposedly took place at Sudbury when they actually took place elsewhere) - this David was the on of Zorobabel Walker and wife Mary Barret Walker.
Zorobabel Walker married Mary Baker, widow 16/10/1787 Mellis, Suffolk (think her maiden name was Barret) and besides David b.1791 they had a daughter Mariah bp.1/6/1794 Suffolk.
I note that David Walker married an Elizabeth Browne 14/2/1814 Cransford, Suffolk and found parents burials:
Zorobabel Walker bc.1761, bur.18/4/1823 Cransford
Mary Walker bc.1750 bur.29/5/1824 Cransford
David and Elizabeth had:
James bp.18/12/1814 Cransford
Eliza bp.22/3/1818 Shottisham
Samuel bp.8/5/1828 (? think this transcription error and should be 1823) Shottisham
Mary bp.5/9/1825 Shottisham
George bp.12/7/1828 Shottisham
Sometime between 1828 and 1841 family had moved to Lancashire and the above children are with David in Bury, Lancashire and looks like wife Elizabeth has died.
As has been explained already, there are no Walker baptisms at Sutton at all, nor do the family ever appear to have lived there.
