Absolutely, they are related. Miles, Thomas, William and Henry arrived in 1610 from Canterbury, Kent, England on a ship captained by Captain Pryn. I am descended from Thomas, who died between 1623 and 1634, leaving a "well-born" son, who is later found in Westmoreland County. Miles arrived in Virginia to establish a salt works, and returned to England several times before finally staying there. His will identifies him as "living in the parish of Holy Cross near and without the walls of the City of Canterbury." (When I went there to locate more information, I learned that this parish no longer exists and its records were lost in the London fire.) Miles was a baker. He died in Canterbury 20 November (2nd Charles) 1626, proved 30 June 1627. He left 200 acres of land "lying in Elizabeth City in Virginia near Salford's Cricke" to his brother John (who was still in England.) Margery may have been his wife, or perhaps the wife of one of his brothers.I have found no later reference to her, so I must assume that she was not his wife, or she would have returned to England with him. That leaves Thomas, William and Henry as her possible husband. Court clerks wrote the family's surname name as they wished. Consequently, it evolved from Prickett (perhaps Pritchett because of the similarity of 'h' and 'k' in ancient handwriting) to Prichard, Pritchard, Pritchardt, et al. Pritchard has been the primary spelling in documents since the early 1700s.
