I have come across the same problem with Thomas Jackson's birthdates.
I have a Thomas Jackson (1680-1746 )born in Northampton, NC (I am not positive of this).
He was said to have had a brother Jeremiah from Boston, Mass. I found a Jeremiah (1706-1735) son of Jeremiah( born 1677) and Hannah Rider born 1680.
Jeremiah(born 1677) said to have been the son of Jeremiah 1652? and Faith Peck.
Jeremiah (1652) said to be a son of Edmund Jackson and Martha Story?
Was there maybe ANOTHER Thomas Jackson that would have been the brother of Jeremiah who was born 1706?
And did they (Jeremiah 1706-1735) and this OTHER Thomas Jackson have a sister named Faith Jackson (1715-17430?
Hope someone has figured this out.
Thanks,
SGM
