"I shall ... begin with a combination made by them before they came ashore ; being the first foundation of their government in this place. Occasioned partly by the discontented and mutinous speeches that some of the strangers amongst them had let fall from them in the ship: That when they came ashore they would use their own liberty, for none had power to command them, the patent they had being for Virginia and not for New England... And partly that such an act by them done, this their condition considered, might be as firm as any patent, and in some respects more sure.
"The form was as followeth : IN THE NAME OF GOD, AMEN. We whose names are underwritten, the loyal subjects of our dread Sovereign Lord King James, by the Grace of God of Great Britain, France and Ireland King, Defender of the Faith, etc. Having undertaken, for the Glory of God and advancement of the Christian Faith and Honour of our King and Country, a Voyage to plant the First Colony in the Northern parts of Virginia, do by these presents solemnly and mutually in the presence of God and one of another, Covenant and Combine ourselves together into a Civil Body Politic, for our better ordering and preservation and furtherance of the ends aforesaid; and by virtue hereof to enact, constitute and frame such just and equal Laws, Ordinances, Acts, Constitutions and Offices, from time to time, as shall be thought most meet and convenient for the general good of the Colony, unto which we promise all due submission and obedience. In witness whereof we have hereunder subscribed our names at Cape Cod, the 11th of November, in the year of the reign of our Sovereign Lord King James, of England, France and Ireland the eighteenth, and of Scotland the fifty-fourth. Anno Domini 1620."

The 1623 Division of Land marked the end of the Pilgrims' earliest system of land held in common by all. Governor Bradford explains it in this way:
"And so assigned to every family a parcel of land, according to the proportion of their number, for that end, only for present use (but made no division for inheritance) and ranged all boys and youth under some family. This had very good success, for it made all hands very industrious, so as much more corn was planted than otherwise would have been by any means the Governor or any other could use, and saved him a great deal of trouble, and gave far better content. The women now went willingly into the field, and took their little ones with them to set corn; which before would allege weakness and inability; whom to have compelled would have been thought great tyranny and oppression."

Plymouth Colony Records, Deeds, &c, Vol. I 1627-1651 is the oldest record book of the Plymouth settlement. It begins with the 1623 Division of Land, recorded in the handwriting of Governor William Bradford. The lands of Peter Brown were among those designated as "their grounds which came first over in the May Floure, according as thier lotes were case" and described in this way "these lye on the South side of the brooke to the baywards."

Plymouth Colony Records, Vol. I also tells of the 1627 Division of Cattle:
"At a publique court held the 22th of May it was concluded by the whole Companie, that the cattell wch were the Companies, to wit, the Cowes & the Goates should be equally devided to all the psonts of the same company ... & so the lotts fell as followeth, thirteene psonts being pportioned to one lot...
"The eaight lot fell to Samuell ffuller & his company Joyned to him his wife (2) Bridgett ffuller (3) Samuell ffuller Junior (4) Peeter Browne (5) Martha Browne (6) Mary Browne (7) John fford (8) Martha fford (9) Anthony Anable (10) Jane Anable (11) Sara Anable (12) hanah Anable (13) Thom Morton Senor (14) Damaris Hopkins.
"To this lott fell A Red [h]eyfer Came of the Cow wch belongeth to the poore of the Colony & so is of that Consideration. (viz) thes psonts nominated, to haue half the Increace, the other halfe, with the ould stock, to remain for the vse of the poore.
"To this lott also two shee goats."

In 1621, King James I authorized the Council for New England to plant and govern land in this area. This Council granted the Peirce Patent, confirming the Pilgrims' settlement and governance of Plymouth. Peirce and his associates, the merchant adventurers, were allotted 100 acres for each settler the Company transported. The Pilgrims had a contract with the Company stating all land and profits would accrue to the Company for 7 years at which time the assets would be divided among the shareholders. Most of the Pilgrims held some stock.
The Pilgrims negotiated a more favorable contract with the Company in 1626. In 1627, 53 Plymouth freemen, known as "The Purchasers," agreed to buy out the Company over a period of years. In turn, 12 "Undertakers" (8 from Plymouth and 4 from London) agreed to pay off Plymouth's debts in return for trade benefits.

The list we have of the 1626 Purchasers comes from the Plymouth Colony Records. It lists the name of "Peter Browne."

22 January 1621 : "Friday the 12^th we went to work; but about noon it began to rain, that it forced us to give over our work.
"This day two of our people put us in great sorrow and care. There was four sent to gather and cut thatch in the morning; and two of them John Goodman and Peter Browne, having cut thatch all the forenoon, went to a further place, and willed the other two to bind up that which was cut, and to follow them. So they did, being about a mile and a half from our plantation. But when the two came after, they could not find them, nor hear any thing of them at all, though they hallooed and shouted as loud as they could. So they returned to the company, and told them of it. Whereupon master Carver and three or four more went to seek them; but could hear nothing of them. So they returning, sent more; but that night they could hear nothing at all of them. The next day they armed ten or twelve men out, verily thinking the Indians had surprised them. They went seeking seven or eight miles; but could neither see nor hear anything at all. So they returned, with much discomfort to us all.
"These two that were missed at dinner time, took their meats in their hands, and would go walk and refresh themselves. So going a little off, they find a lake of water, and having a great mastiff bitch with them and a spaniel, by the water side they found a great deer. The dogs chased him; and they followed so far as they lost themselves, and they could not find the way back. they wandered all that afternoon, being wet and at night it did freeze and snow. they were slenderly appareled, and had no weapons but each one his sickle, nor any victuals, they ranged up and down and could find none of the savages’ habitations. When it drew to night, they were much perplexed; for they could find neither harbor nor meat; but, in frost and snow, were forced to make the earth their bed and the element their covering. And another thing did very much terrify them; they heard, as they thought, two lions roaring exceedingly for a long time together, and a third that they thought was very near them. So not knowing what to do, they resolved to climb up into a tree, as their safest refuge, though that would prove an intolerable cold lodging. So they stood at the tree’s root, that when the lions came, they might take their opportunity of climbing up. The bitch they were fain to hold by the neck, for she would have been gone to the lion. But it pleased God so to dispose, that the wild beasts came not. So they walked up and down under the tree all night. It was an extreme cold night. So soon as it was light, they traveled again, passing by many lakes and brooks and woods, and in one place where the savages had burnt the space of five miles in length, which is a fine champaign country, and even. In the afternoon, it pleased God from a high hill they discovered the two isles in the bay, and so that night got to the plantation, being ready to faint with travail and want of victuals, and almost famished with cold. John Goodman was fain to have his shoes cut off his feet, they were so swelled with cold; and it was a long while after ere he was able to go. Those on the shore were much comforted at their return, they on shipboard were grieved at deeming them lost."
