Sources show that Christopher arrived in Warwick County, VA in 1622 aboard the "Frances and John" and settled there on 450 acres, the patent to which was made 15 September 1636.
It is unclear who he came with since he would have only been 11 at the time of his arrival. His parents both died in England. He may have come over with his older brothers.
