Thank you for the information for Emily Watson.I think I am looking for Waltons, but the Watsons, Waltons and Grococks may have all been in the same social circle in London.
I received the marriage record for Sabra Ann Walton and Thomas Cockrill who married on 19 August 1815 at Saint Luke Old Street, Finsbury, London, England.
The marriage record for Sabra Ann Walton and Thomas Cockrill states that she was a widow when she married Thomas Cockrill, so Walton was not her maiden name.
I received the marriage record of William and Sabra Ann Walton who married in 1810.Her name was Sabra Ann Birch when she married William Walton.Hopefully, Birch was her maiden name.They had a daughter Mary Ann Walton in 1811.
2) At Familysearch.org, I found:
WILLIAM WALTON Male
Event(s): Birth: Christening: Death: Burial:
Marriages: Spouse: SABRA ANN BIRCH Marriage: 27 NOV 1810 Saint James, Westminster, London, England
I thought there would be more genealogy data in the genealogy databases for the English surnames that I am researching.I was wrong.
If I find any information connecting your William Grocock to the Elizabeth Grocock in the will, I will share the information with you.
