I've been working on other family lines since August, so I'm a little "cold" on the details of the Seavers.However, here's what I see as the big picture:
In the 1780s and 1790sthe family of a Henry & Elizabeth Se(a)ver(s) was in SW VA; some of their descendants moved into NE TN in the 1790s and early 1800s.Henry & Elizabeth are said to have had at least 3 children:Elizabeth,Jacob and John.There is very strong evidence that my husband's grgrgrgrandfather, William, was another child; William's death is amply documented as about 1814 in Washington Co, VA, probably in the part that became Scott Co, VA that sameyear.We *speculate* that this William may have been born about 1770--that is based on the fact that his oldest child was born about 1794 and the fact thathis brother Jacob is known to have been born 1773.
There was another William b. @1752, who married Catherine Peck in VA in the 1790s.They were in Knox/Anderson Co., TN by 1801--about 100 miles from the Hawkins Co, TN/Scott Co, VA Se(a)ver(s).I speculate that the William of Knox/Anderson was somehow related to the family of Henry & Elizabeth of SW VA, but I don't know what the relationship might have been.Given the ages that we know, my best guess--but it is only a guess-- is that William of Knox could have been a younger brother, cousin or nephew of Henry of SW VA.My knowledge of this Knox/Anderson family is not based on my own research, but on what others have written about it.
One of the intriguing links between these two families is that Henry & Elizabeth's daughter Elizabeth married John Lamar and William & Catherine's daughter Mary "Polly" married William Lamar.
Some of Henry & Elizabeth's grandchildren settled in Hawkins Co., TN and at least one granddaughter settled in Grainger Co.At that time Grainger Co. bordered Hawkins Co. on the north and Knox/Anderson on the south.
The William of SW VA (the one who died in 1814) had several sons and grandsons who were wagon makers and wagoners.It is known that one son carried goods from Baltimore to Knoxville, while the home base after 1818 was Wythe Co, VA, but with other brothers in Hawkins, TN and an uncle in Scott, VA (who later moved to Switzerland Co, IN)--all on the route down the Shenandoah to NE TN and then down the valley to Knoxville.
So, there are a number of "coincidences" thatlead to speculation about a connection between these two groups of Se(a)ver(s).Plus, it appears that the only names they used for their sons were William, Henry, John and Jacob!
So, what does this have to do with the AL, GA and FL Se(a)ver(s)?William of Knox/Anderson Co. had a large family, and it is thought that some of his sons migrated south from TN.Some stayed in the Knox/Anderson area and have descendants there today.One or more of William's sons migrated to MO in the 1840s, taking William with them.William died there @1852.The extended family can be found in the 1850 Nodaway Co, MO census.
I don't know where your William b. 1788 or his father Henry would fit in or how the John b. 1786 could fit.The evidence that the William who died in 1814 is the son of the Henry & Elizabeth of SW VA is very convincing, which makes me think that your Henry couldn't be the Henry of SW VA.Perhaps your Henry could be a first cousin or nephew.
When I finish my current project, I plan to start on more "heavy-duty" Seaver research, starting with the VA personal property tax lists, which started soon after independence.Because they were taken every year, individuals who were missed in the census sometimesshow up in these lists. I'll be sure to post my findings.
