Swebby, Kerryb,
Thanks for the help.
Unfortunately, I know little about Ann Boniface/Sinnock. I believe that she may have been the mother of a Henry Sinnock that married Mahala Cruttenden in Bexhill on 6 Nov 1843. According to Henry's marriage certificate (thanks to cath151 for the cert), Henry's father was Boniface Sinnock. Henry and Mahala emigrated to the US shortly thereafter and lived in Stark County, Ohio. One piece of information suggests that Henry was born in Hastings, Sussex. His birthdate is in the range of 1813-1816.
I found the following entry in the 1841 census that could well be the Ann Boniface that I am looking for. It would make her DOB as being ~ 1786.
Class: HO107; Piece 1114; Book: 10; Civil Parish: Hailsham; County: Sussex; Enumeration District: 2; Folio: 19; Page: 2;
Summer Heath (part of), Hailsham, Sussex
Ann Boniface; age 55
Henry Sinnock; age 25
Frederick Sinnock; age 20
All born in Sussex
There are two Ann Boniface's listed as dying between 1841 and 1851 in Hailsham District.
The following entry in the East Sussex Archives may be relevant
Overseers of the Poor: apprenticeship papers - ref. PAR353/33
FILE - Apprenticeship indenture - ref. PAR353/33/105 - date: 19 May 1824
[from Scope and Content] William Sinnock (16 yrs), the son of Ann Sinnock widow, apprenticed to Thomas Burfield of Hailsham, rope and hemp maker
