The 1850 Census for Bedford Township, Coshocton County, Ohio, listed Nathan Wright, age 87 and born in Pennsylvania.
Next door to Nathan Wright in the 1850 Census was Nathan Wright, age 50 and born in Pennsylvania, with son Achor Wright, age 23 and born in Ohio.
As you may already know, Marriages Coshocton County, Ohio, 1811-1930, compiled by Miriam C. Hunter, 1967, listed the marriage of Aches or Achro Wright and Eliza Stafford on July 2, 1829, in Coshocton County, Ohio.
And the 1830 Census for Bedford Township, Coshocton County, Ohio, listed the following:
1. Nathan Wright, age 60 to 70,
2. Nathan Wright, age 30 to 40, and
3. Achor Wright, age 20 to 30, with one female, age 20 to 30, and one female, age 0 to 5.
This seems pretty clearly to be your Nathan Wright family you are researching.
WorldConnect listed the marriage of Nathan Wright and Hannah Worley on August 29, 1786, in Bedford County, Pennsylvania.
If there is no reason to doubt the 1850 Census listing of Pennsylvania as the place of birth for Nathan, Sr., then it would seem likely that the home in Pennsylvania that family legend says he was taken to would be in Bedford County, Pennsylvania.
Although you may have already done this search, I suspect your best bet would be to search for Wright families in Bedford County, Pennsylvania, in the period 1760 to 1790, especially in the early part of that period with persons named John or Moses. Your Nathan would probably be related to one of those families.
The deed records would probably be the best place to start and then any tax lists that might have been kept.
If Nathan was still young when taken back to Pennyslvania after his parents' deaths, then his family probably moved from Pennsylvania to Virginia or North Carolina after his birth in 1762 and before he was a teenager. So I would look for a sale of land by a John or Moses Wright between 1762 and 1775 in Bedford County, Pennsylvania. That might give you the year of the family's move. Then I would search for a purchase of land in the border counties of Virginia and North Carolina within 2 years before that move date and 3 years after that move date for the same named Wrights. This might enable you to pin down the county to which the family moved and where the probate of the father's estate would likely have been had. Then I would search the probate records of that county for a John or Moses administration after the move date and prior to about 1776.
Hope this is of some help and good luck in your search.
