I would be interested in your information
that shows that the John Fann who died in
Orange County was married more than once.

The only wife I ever found him with was
Elizabeth. She NEVER remarried after his
death. The Orange County censuses from
1800-1810-1820-1830
consistently show her living with no husband.
She died in 1837 in Orange County and most
certainly did NOT go to TN. There are
extensive loose probate files in Orange
County under both John and Elizabeth's names
that show this.
One of the eldest children was Judith Fann,
who married John Walker. She was the only
one of the children who remained in Orange
County until Elizabeth died. Since it is
hard to imagine her remaining behind to care
for a stepmother, when the stepmother's own
children left, I strongly suspect that
Judith was also a daughter of Elizabeth.
Since I calculate Judith's BD as around 1774,
and Elizabeth's as just before 1760, I
suspect that John Fann married Elizabeth
when she was only about 13 yo.
It is true that many of John and Elizabeth's
children did migrate to middle TN.
By 1837, when her mother died, Judith had
been a widow for many years. She and her
daughters then migrat3ed to the same area
of middle TN where her own brothers and
sisters had gone before, and where her own
son had gone.
The Elizabeth you refer to as having migrated
to TN was prob a descendant of John Fann,
and NOT his wife.
Prior to Orange County, John Fann is found
in Warren county, as is Willoughby Fann.
Willoughby is such an unusual name that it
almost has to be the same person listed in
the early 1700s in the parish records from
Richmond County, VA.
There is also a younger John Fann in
Richmond County who was born in the 1720s
who is a grandson of the John Fann who was
married to Mary Stone.
The John Fann in Warren County vanishes from
there and shows up in Orange County right
about the same time. The 1785 census of NC
for Warren County shows them in that county
also. It is not particularly helpful in
figuring out the ages of older men and very
young males, but if John is the same one as
the Richmond County John Fann, then he would
have been 60 years old at that time and would
fit very nicely into the category where
there is one male who is either very old or
very young.
Willoughby and John both are found in brief
mentions in Lunenburg County.
John apparently served in one of the colonial
wars and is listed in Henings Statutes as
being from Lunenburg County.
Willoughby is listed in a list of persons
who have removed to other places and it
states that he is in NC.
There are a couple of Fanns of other names
found in that same area of Virginia that are
the same names as some found in Richmond
County. So it appears that many of them may
have just picked up and moved to southern VA
and NC.
