Edward Mayo appears as a witness to the Will of Thomas Austin of St. Philip, March 23, 1672.
p 569
In the will of George Maggs, a Quaker, dated "17th day of ye 4th month called June, 1677," he mentions grandchildren Sarah, Ann, Elizabeth, and Edward Mayo, children of Edward and (his daughter) Sarah Mayo. Edward Mayo to be esecutor in trust to see his will performed. Daughter Sarah Mayo to receive "one gold diamond cut ring."
[And here is something even more useful: The testator intended that Edward Mayo's testimony should be received without an Oath, that he should administer the estate without the usual formalities being complied with. This suggests perhaps that Edward Mayo was also a Quaker, prevented by his faith from taking oaths.]
... It appears from the marriage records that his daughter Sarah had been maried in the parish church of Christ Church on 2 Sept. 1666 to Edward Mayo (who was named in error as Edward Mays). It is probably that Edward Mayo and family afterwards seceded, and embraced Quaker principles before the Will of George Maggs was made. ...
