In the cemetery of Springfield, Hampden county, Massachusetts, stands the elaborate tomb of Captain William Day, with his wife Rhoda, and his son Captain James Day. The inscriptions and images on this monument are the starting point for exploration of what may be a very very complicated life:

Capt. Wm. Day sailed in command of a frigate with a picked crew, encountering a fleet of five French ships in the Bay of Biscay. The admiral's ship larger than his own was considerably in advance of the others. He engaged and captured her before the others came up, and neither vessel being much injured he divided his force with the captured ship and the others coming he attacked them with such spirit that they all surrendered and he brought them all safe into Plymouth.

The scene on the other side of this monument is taken from a portrait painted at the time, now in possession of his family. Capt. William Day soon after the war retired from the sea and settled in Sheffield, Mass. where he died. He was an active patriot in the revolution. He lived and enjoyed the esteem and respect of his friends and neighbors. His remains with those of his wife were removed from Sheffield and placed under this monument. This monument is placed here by his grandson Thomas D. Day of St. Louis.
On the opposite side, an inscription on the upper sarcophagus, and a caption to the battle scene, give a little more information:
In memory of Capt. Wllliam Day. Born in Springfield Oct. 26, 1715. Died in Sheffield March 22, 1797. Aged 82 years.

The action represented here was fought during the French War about the year 1760 by Capt. William Day.
These inscriptions contain a great deal of falsehood, and a great deal of concealment (Plymouth Massachusetts, or Plymouth England? "Active patriot" in what way? ...). Investigation of contemporary records reveals many possibilities, some of which can be firmly identified as red herrings that have led to mistakes and misunderstandings by historians and genealogists, but others of which remain, so far, tantalising. What follows is a tabulation of information which will help to begin the process of untangling Captain William Day of Massachusetts, 1715-1797, from the numerous people he never was.

[re settlement of the Housatonic land purchase]: As an initiatory step toward the settlement of the Lower Township, the committee called a meeting of the petitioners or proposed settlers, to be held at the house of John Day, in Springfield, on the 13th of March 1723, but, as a public fast had been appointed to be observed on that day, the time of the meeting was postponed to the 19th. At this meeting fifty-five persons, each having paid the sum of thirty shillings to the committee, were accepted by them and were to have lands granted to them, on condition that each should build a suitable house and till twelve acres of land within three years' time.
On the 9th of March, 1726, at a meeting of the committee, it was determined "that two of the committee, at least, should go to Housatonic to make something of a survey of the same, in order to a division of the two towns ..." "
[not sure if these dates are Old Style or New Style] [disputes with New York prevented settlement for some years, hence the delay of apportionment until 1733]

[possible future (1747) wife of William Day]
"By March of 1726, the settling committee was ready to make plans for surveying the tract in order to divide the townships and lay out lots at least in the Lower township.
The Lower Township was partitioned into five divisions, two of which were the minister’s right and the school land and reached as far as the Indian reservation. Shares in the other three divisions were sold to 39 prospective setters.
During the year of 1733-34, the new settling committee visited the town several times, admitted colonists, surveyed the land, outlined the plots, and recorded titles. The committee records describing the lots laid out in the Lower township have been preserved and are stored in the town hall in Sheffield.

BOSTON, July 28.
Last Tuesday [26 or 19 July] arrived Capt. Day from Lisbon, by whom we are inform'd, That he sail'd from thence on Sunday the 17th of June N.S. [nominally, 17 June was Monday- confusion may have arisen from the maritime policy of measuring days from midday to midday] and that the Day before, in the Morning, a Post from Madrid, brought certain Advice, that the Court of Spain had acceded to the Cessation of Arms in the same Manner that was agreed upon between Great-Britain, France and the States-General; and that Hostilities on the part of Spain were accordingly to cease at the same Period. This News was told Capt. Day by a Merchant of very good Credit at Lisbon just before he sail'd, who shew'd him a Portugueze News-paper, in which it was inserted; and as Capt. Day had all his Letters and Papers for this Place on board a Week before he sail'd, some of which Letters intimate, that the Spaniards stood out and would not sign, nor was there any likelihood of it, so now the Gentleman told him the contrary, and said, that he might inform any Person in New-England, That the above News of Spain's agreeing to the Cessation might be depended upon.
