Yes I do have that book. There are two mentions of Weldon Plantation. I will quote from page 143. "Samuel Weldon, A James City County justice and sheriff, who immigrated to VA around 1675, married Sarah Efford, heiress to several hundred acres of land approximately four miles west of Middle Plantation. Samuel and Sarah Weldon's son, Benjamin, inherited his maternal grandfather's land and developed it into what by the mid 18th century was a relatively well known local landmark." This info is cited from Nugent, Cavaliers, "Virginia Gleanings in England," Virginia Magazine of History and Biography 13 (July 1904): 195-196. The Efford-Weldon property enveloped the land upon which the Williamsburg Memorial Park is located.
Page 197 "Benjamin Weldon's plantation was about four miles from Williamsburg and was a frequently used reference point in real estate advertisements, suggesting that it was well known. Nearby was Lilliput, a plantation that by the 1760's belonged to the colony's treasurer, John Robinson of King and Queen County. Benjamin Weldon succumbed to financial hardships after the Rev. War."
