The August 1850 Census shows Barnette at age 30, making birth year abt 1820.
Martha age 25 making birth year abt 1825.
William age 5 making birth year abt 1845.
Susan age 3 making birth year abt 1847.
Sara age 9 months making birth year 1849.
Also show Barnette birth place as Buckingham
Martha, Susan, and Sara birth place as Pittsylvania County.
And surprisingly William birth place as North Carolina.
John Abram, Andrew Solomon, Betty, and William David(?) must have all been born after the 1850 census, so I will begin searching later census records for their birht dates.Carol's previous posting is the first I have ever heard of William David so I will be very interested to see him in birth records or census records.
