Often partnerships were formed for the importation of servants, in which cases the patents were made out jointly. Among the more interesting are patents to Robert Beverley and Henry Hartwell, to Thomas Butt and Thomas Milner, to William Bassett and James Austin, to Thomas Blunt and Richard Washington. When associations of three or more persons were formed for the importation of servants, a not infrequent occurrence, the number of headrights is unusually large and the grants patented in consequence extensive. Thus Edmund Bibbie and others are credited with 3,350 acres, Robert Ambrose and others with 6,000, George Archer and others with 4,000.[3-26] It is clear, then, that the size of the average patent in the Seventeenth century is not an indication of the extent of the average plantation. If economic conditions were such as to encourage large holdings, extensive farms would appear regardless of the original patents, for the small proprietors would be driven to the wall by their more wealthy rivals and forced to sell out to them. On the other hand, if the large planters found it difficult to secure adequate labor they would of necessity have to break up their estates and dispose of them to the small freeholders. That the latter development and not the former actually took place in Virginia during the Seventeenth century a careful examination of the country records makes most apparent. Over and over again in the records of various land transfers it is stated that the property in question had belonged originally to a more extensive tract, the patent for which was granted under the headright law. A typical case is that of John Dicks who purchased for 8,500 pounds of tobacco, "all the remaining part of 900 acres gotten by the transporting of 19 persons."[3-27] Similarly we find John Johnson in 1653 selling to Robert Roberts half of 900 acres which he had received by patent.[3-28] In 1693 John Brushood sold to James Grey 200 acres, a part of 5,100 acres originally granted to Mr. Henry Awbrey.[3-29] Such cases could be multiplied indefinitely.
