From whom/what source does this quote in Overview come:
"a report of his will written 27 September 1722 says he died 29 September 1722, two days after making his will."
I question the death/burial date that seems to lack solid evidence. Unless there's a primary source or sold secondary sources proving his date of death, it might be best to show a range for Thomas' death:
between 27 Sep 1722 and 27 Nov 1722 — i.e., between date of his will and the inventory/probate date.
Find A Grave's volunteers are notorious for slipshod research and lack of source(s) supply.
CONFIRMATION FOR DEATH DATE: 29 Sep 1722.
