This labels William Price as 'esquire,' and as being from Winchester, England. I think this William Price, married to Susan Tracy, may be a different one than the one who accompanied his father to Virginia.
In 'North America, Family Histories, 1500-2000, The Tracy Family / The Winslow Family,' it says that the Susan Tracy who was the daughter of Sir Paul Tracy, baronet, was: "Born about 1606, married to William Price of Winchester, one of the grooms of the King's Privy Chamber. She died March 13, 1632, "before she had been married full 14 weeks." "
So, this means that they were married sometime in December, 1631. I don't know if she died in England, but I think that if she died in Virginia, this would've been mentioned.
