Even though servants were not granted land by the colony at the expiration of their service, a substantial number soon became landowners. The exact proportion of servants that became landholders after 1624 cannot be determined in the absence of a complete census. However, an examination of the land patents and the list of headrights makes possible some estimate of the percentage of landholders that had once been indentured servants. The conclusions cannot be final and are subject to limitations. Identification presents a problem because of the frequency of the same name as Smith or Davis and because of the omission of middle names. The problem is further complicated by the fact that headrights were often transferred by sale. A person entitled to a headright claim on the frontier may not have wished to settle there; rather he may have preferred to sell his headright claim and purchase land in an established county. As a result of the sale of his headright claim, his name may have appeared in the headright list as the basis for the claim for someone else even though he had not been an indentured servant. Therefore, all persons so listed under the headright claim cannot be considered indentured servants. Fully aware of the limitations just suggested and equally conscious that estimates in the absence of more complete records cannot be final, Professor Thomas J. Wertenbaker in his _Planters of Colonial Virginia_ summarized his analysis of patents and concluded that both before 1635 and in the following two or three decades, thirty to forty per cent of the landholders of Virginia came to the colony as indentured servants. Professor Wertenbaker also indicated general agreement with conclusions drawn by William G. Stanard about the proportion of immigrants that were indentured servants. From an analysis of the patent rolls from 1623 to July 14, 1637, printed in the April, 1901, issue of the _Virginia Magazine of History and Biography_, Stanard estimated that seventy-five per cent of immigrants from 1623 to 1637 were imported under term of the indenture. Out of 2,675 names on the rolls, 336 entered as freemen at their own cost and an additional 245 persons were believed for the most part to be of the same status although there was some uncertainty about this group. Transportation expenses were paid by others for 2,094. From these numbers, the conclusion was reached that 675 persons on the patent rolls were freemen, including women and children; the remaining 2,000 were servants and slaves, the latter in very small number at this time. Thus the analysis roughly confirms the conclusion that three-fourths of the immigrants during this period were indentured servants.
