Bertie tax record abstracted by Joe H Cobb: "In 1778 he [Edward Cobb] was listed in Humphrey Hardy's district along with Henry Cobb Jr and Hannah Cobb, who was the widow of Thomas."

In 1765 Edward and Henry Jr were designated by the sheriff to be petit jurors. The word "fined" was written by Edward's name. 
In 5 Dec 1766 he bought 150 ac of land from Richard and Mary Bell of Craven Co, SC  for 35 pounds. Wit were Alexander How and John South.  land was located on the Horse Spring Branch and Bear Swamp.

June Ct 1767 Edward Cobb petitioned for permission to build a water grist mill partly on the land that belonged to Samuel Moore.  When Samuel Moore was summoned, he petitioned to build a grist mill over the same stream.  Edward's request prevailed.

In June 1770 Edward Cobb petitioned to build a public grist mill across Horse Spring Branch. This time it affected the land of John Moore.  again Edward Cobb's request was granted.
