Readers of volume II of my book on the Pettus family will find good evidence in appendix S that the immigrant Thomas from Norwich, England, was first married to Ka-Okee, daughter of Pocahontas and Kocoum, after Thomas settled in the colony. After Ka-Okee's death c1637, Thomas married Elizabeth (Freeman) Durrent, widow of Richard Durrent, deceased.
Whether Thomas's first marriage was recognized by the Church of England depends upon whether or not Ka-Okee converted to Christianity, but the name of Thomas and Ka-Okee's daughter, Christian, suggests that Ka-Okee had been baptized into the church.
As the evidence for Thomas's marriage Ka-Okee had not come to my attention until the summer of 2012, my two volumes were written on the basis that Thomas and Elizabeth were the progenitors of the Pettus family in Virginia. Once the new evidence came to my attention, I thought at first that Thomas had descendants by both wives. In particular, Thomas and Elizabeth had a son Thomas, who was an orphan in 1672.
Thomas II may have married twice. Assuming that was the case, nothing is known about his first wife (despite claims that he married a Dabney). His only wife of record was Elizabeth Burgh of Nansemond County. At the time I wrote my book, I had concluded that the children of Thomas II (probably by his first wife) were Elizabeth, who died before 1700, and Stephen, who married Mary Dabney.
The problem is that known male descendants of Stephen and Mary have Y-DNA that matches the Y-DNA of known descendants of Powhatan. The only way for this to work is that Stephen was not the son of Thomas II. More likely Stephen was the son of an earlier Stephen Pettus who was settled in New Kent County by 1662.
These circumstances lead me to believe that the earlier Stephen was the son of Thomas I and Ka-Okee. Another result is that Elizabeth, the orphan daughter of Thomas Pettus II was his only child. Thus, all known Pettuses born in Virginia probably trace back to Ka-Okee, her mother Pocahontas, and her grandfather Powhatan.
