Heading from the Indenture of David Thomson and his three partners, of Plymouth, England, laying out the contractual terms of their assignment to establish one or more settlements in New England in exchange for land (November, 1622). David Thompson is the principal member of this partnership, and is identified as a "gentleman":

Final paragraph from the Patent drawn up by the Council for New England (December 30, 1623) specifying their plan to bring order to the future development of New England by sending Fernando Gorges’ son, Robert, to serve as their “Lieutenant General” in the colony of Massachusetts. After Robert Gorges' completed the setup of an administrative framework, he was expected to return to England, and David Thomson was to be left behind to serve as "attorney" for the Council and oversee the Council's business in Gorges' absence. You will notice that Thomson is identified as "Gent." (Gentleman) in the formal declaration. (Background: Reports had been received that previous groups sent over had been engaged in “abuses” “tending to the scorn of our nation” through “mixing themselves with their women, and other beastly demeanors, tending to drunkeness to the overthrow of our trade and dishonor of the Government”. Robert Gorges was to bring legal authority and control to the colony and “regulate the estate of their [the previous settlers] affairs and those abuses”) :

And lastly know ye, that we the said Council have Deputed, Authorized, and Appointed, and in our place and stead [role or function] have put David Thomson, Gentleman, or in his absence any other person that shall be their Governor, or other Officer unto the said Council, to be our true and lawful Attorney and Attorneys, and in our name and stead to enter into the said Lands, and other the Premises with their Appurtenances [legal authorities or mechanisms], or into some part thereof in the name of the whole, for us and in our names to have and take Possession and Seizin [permanent and absolute control of land] thereof, and after such Possession and Seizin thereof, or of some other part thereof had and taken, then for us and in our name deliver the same unto the said Robert Gorges or his Heirs, or to his or their certain Attorney or Attorneys to be by him and his heirs appointed in that behalf, according to the true intent and meaning of these Presents [documents], Ratifying, Confirming, and Allowing, all and whatsoever our Attorney and Attorneys shall do in or about the Premises, or in part thereof by virtue of these Presents. In witness whereof, we have affixed our Common Seal, the thirtieth day of December in the year of the Reign of our Sovereign Lord James by the Grace of God of England, France and Ireland, King, Defender of the Faith, etc., the twentieth [1623], and of Scotland the fifty sixth.

We, the Council of New England, have authorized and appointed David Thomson to serve as our attorney in all matters regarding establishing and carrying out our authority in the lands in our possession in New England, while in our absence, and report all matters involving this authority to Robert Gorges, or his successors, or to the attorneys representing them.

Original Plymouth colonist and the second governor of the colony, Edward Winslow, kept a journal of events that occurred at Plymouth Colony between 1622 and 1623, the second and third years of the Plymouth project. A passage from the Fall of 1623 describes the arrival of David Thomson in the service of Miles Standish, delivering much needed food relief to the colonists who had been suffering from several failed resupply attempts from England, and from an unusually harsh drought. Winslow identifies Thompson as a "Scotchman" on his arrival:

At the same time Captain Standish being formerly employed by the Governor to buy provisions for the refreshing of the Colony, returned with the same, accompanied with one Mr. David Tomson, a Scotchman, who also that Spring began a Plantation twenty five leagues northeast from us, near Smiths Iles, at a place called Pascatoquack, where he liked it well. Now also heard we of the third repulse [failure to complete the trans-Atlantic journey] that our supply had, of their safe though dangerous return to England, and of their preparation to come [return] to us. So that having these many signs of God's favour and acceptation, we thought it would be great ingratitude, if secretly we should smoother up [brush aside or disregard] the same, or content ourselves with private thanksgiving for that which by private prayer could not be obtained. And therefore another solemn day was set apart and appointed for that end, wherein we returned glory, honor, and praise, with all thankfulness to our good God, which dealt so graciously with us, whose name for these and all other his mercies towards his Church and chosen ones, by them be blessed and praised now and evermore, Amen.

Thomas Morton, an early New England colonist, came to Massachusetts in 1624 as part of a government-sponsored trading venture. Much has been written about his controversial actions and their consequences while establishing a fur trading cooperative with the local Algonquian tribes, with much of it stemming from his belief that Native American culture was superior to that of the neighboring English, especially the Puritans of Plymouth Colony. While studying Native Americans, Morton apparently came upon David Thomson and discussed Native American origins, which he subsequently mentions in his later work, The New English Canaan, published in 1637. In his mention of Thomson, he describes him as a "Scottish gentleman":

And why should any man think the Natives of New England to be the gleanings [collected people] of all Nations, only because by the pronunciation and termination their words seem to trench upon [come close to] several languages, when time hath not furnished him with the interpretation thereof. The thing that must induce a man of reasonable capacity to any manner of conjecture of their original [origin], must be the sense and significance of the words, principally to frame this argument by, when he shall draw to any conclusion thereupon: otherwise he shall but run round about a maze (as some of the fantastical tribe use to do about the tythe of mint and comin.) Therefore, since I have had the approbation [approval or agreement] of Sir Christopher Gardiner, Knight, an able gentleman that lived amongst them, and of David Tompson, a Scottish gentleman that likewise was conversant with those people, both Scholars and Travellers that were diligent in taking notice of these things, as men of good judgement, and that have been in those parts any time, besides others of less, now I am bold to conclude that the original [origin] of the Natives of New England may be well conjectured to be from the scattered Trojans, after such time as Brutus departed from Latium[Rome].

Why would anyone think the Natives of New England to be descended from people of other nations only because their language seems similar in pronunciation and structure to other known languages of the world? A critically thinking person would have to know the meaning and contextual basis of the language's use before drawing any conclusions as to the possible origins of such a people. Therefore, before drawing my conclusions, I spoke with and found agreement with Sir Christopher Gardiner, Knight, a gentleman that lived among them, and David Thomson, a Scottish gentleman who also understood the languages and customs of the Natives. Both were well-educated, well-traveled men of good judgment, and have been living in close proximity to the Natives for some time. Their opinions, along with other people of lesser reknown, have led me to the conclusion that the origin of the Natives of New England may well be the scattering of the Trojans after the exile of Brutus and his people from Rome.
