I have seen several lists of the children of Joseph & Martha Newberry Thames. Here is my version of the proven children of Joseph & Martha based on Joseph's Will written 11 October 1780. Joseph Thames died shortly after writing his Will.
Martha appears on the Bladen County Tax Exempt List of 1781. Only an unmarried woman could own property at that time. Martha was a widow in 1781. The Joseph who appears on that tax list is her son. Martha's Will is written 11 February 1814 and is recorded June 1815. She names four sons Joseph, Thomas, John, and Samuel. I think this is according to age, Joseph being the oldest. Jesse and William are dead so are not named. Martha names Joseph and John executors because they are the only sons she has left in NC.
Joseph names "my sons Jesse Thames, Joseph and William Thames the sum of five shillings each" then he names "my four children Thomas, Martha, John and Samuel Thames". This indicates, to me, that his three sons Jesse, Joseph and William were of age, twenty-one years. The other children had not yet come of age.
Jesse born 1753 Bladen Co. died 1797/98 in Cumberland Co. NC Based on Bladen Co. tax list and deeds. Elizabeth named widow of Jesse Thames (CC, DB-18, Pg-199, May 6,1799). Mrs. Elizabeth Thames declares her age as 60 years when she marries Joseph Butlar on Feb. 15, 1810 Raleigh NC newspaper announcement.
Joseph born August 15, 1758 Bladen Co. died August 1, 1819 Cumberland Co. NC Based on Bladen Co. tax list and tombstone.
William born 1759 Bladen Co. died January 18, 1813 Cumberland Co. NC Based on Bladen Co. tax list and Raleigh NC newspaper obituary. (Joseph & William must have been born within thirteen months of each other)
Thomas born 1764 Bladen Co. died after 1814 place unknown. Based on Bladen Co. tax list & mother Martha's Will written Feb. 11, 1814.
Martha born 1765/67 Bladen Co. married Malachi Burges (CC, DB-18,Pg-199, May 6, 1799) Three children by 1790 census-Just guessing on birth year!
John born 1770 Bladen Co. died March 26, 1832 Cumberland Co. NC Based on Bladen Co. tax list & obituary in Fayetteville Observer April 10, 1832
Samuel born 1772 Bladen Co. died after 1814 place unknown Based on Bladen Co. tax list & mother Martha's Will written Feb. 11, 1814
It would appear that only two of the sons of Joseph & Martha ever left NC, Thomas & Samuel. The other four died in Cumberland County, North Carolina.
