There are several pedigrees posted which lead back to Henry Tyler (1604-1672) in Williamsburg, Virginia Colony.
When one looks at the results page, a vagrancy appears in that some descendants have an I-M223 haplotype and others have an R haplotype.
I also claim that John Tyler as my ancestor and he resided in St. Paul's Parish in Hanover County, Virginia, and I am of the I-M223 haplotype.
The R haplotypes use a pedigree which link back through a John Tyler of St. Paul's Parish in Chowan County, North Carolina.
I believe a problem exists with the source of the genealogical information tying the descendants of the North Carolina John Tyler back to Henry Tyler of Williamsburg in Virginia.
There is scant paper evidence remaining, but what is available does not show John Tyler of Hanover County, Virginia moving to North Carolina as Rebecca Tyler Allen published over a decade ago. In fact, records from St. Paul's Parish in Hanover County indicate John Tyler is present in Hanover in 1619, many years after Rebecca Tyler Allen shows him in Chowan, North Carolina.
Another researcher has suggested that the "Chowan" Tyler clan sprang from the Tyler family on the eastern shore of Maryland.
I have tried to communicate with Rebecca Allen or her representative, but my inquiries were met with a very "down-the-nose" attitude and no meaningful discussion was had.
My belief is two different John Tyler men were alive and raising their families simultaneously in two different St. Paul's Parishes and these two families have been confused, for reasons unknown to me, and this error is being perpetuated.
