Nancy Bowles, 100 years

The marker at the grave of Thomas Bowles (d. 1846) tilts to the right as you look at it, almost as if it is struggling under the burden of several broken stones that it supports.

One of the broken stones is the gravestone for Nancy Bowles (d. 1843), who lived to be 100 years old. That is quite an accomplishment in any century.

THOMAS BOWLES
died Jan. 10,
1846:
Aged 6[? yrs, ?? mos] & 5 d’ys.

In memory of
NANCY
Wife of Hugh
Bowles who died
Mar 4, 1843 aged
100 yrs.
The first question that comes to mind is: How are Thomas and Nancy related?

Not husband, wife. Son, mother? At least one (unsourced) Ancestry tree suggests the latter, but this mystery requires more research.

In the meantime, I am planning another trip to this cemetery soon. Could there be relationship hints that I missed on my first visit?
