Well, Hello again, Dolly! (Sorry, couldn't resist that...)
Are you sitting comfortably? Then I'll begin...
Managed to get to the CCRO a day early, and headed for the Sutton registers.
Confirming what you already knew, though one or two added "extras":
Baptisms to William WHETSTONE, labourer, and Elizabeth:
06-12-1818: Jane, daughter of William and Elizabeth. (Burial Jane WHETSTONE, 26-02-1822 aged 3)
07-03-1822: Thomas, 2 years, son of ditto (Burial Thomas WHETSTONE 03-04-1825 aged 5)
28-05-1823: Jane, d. of ditto
16-04-1825: William, s. of ditto (Burial William WHETSTONE 02-08-1826, infant)
02-09-1827: Mary d. of ditto
14-03-1830: Sarah, d. of ditto (Burial Sarah WHETSTONE 02-01-1832, infant)
04-11-1832: John, s. of ditto
06-10-1834: Robert (Your ancestor!), son of ditto
So as you can see poor William and Elizabeth WHETSTONE did not have much joy with raising their family, as only Jane, Mary, John and Robert survived into adulthood. The final burial is for their mother, I presume:
Burial: 11-06-1869: Elizabeth WHETSONE, 78
There's lots more, Dolly, as I had my map with me and had to search in nearby Parish Registers, but I'm being shunted off this computer by my daughter for a while. But I'll return with the rest shortly, perhaps via PM...
