These data indicate:

Gender and Type	Age Class	Therefore Born	Individuals Inferred
1 free white males	16 or over	in or bef. 1774	= Silas (b. 1752)
1 free white males	15 or under	1774-1790	= Seth (b. 1776)
3 free white females	all ages	in or bef. 1790	= Wife-2? housekeeper? = Sarah (b. 1778?) = Abigail (b. 1778)

That Silas had no additional children suggests the adult woman in this and later censuses was possibly a housekeeper/nanny, not a second wife.  Also in Brandon:  Joshua GOSS and Edward CHENEY.  List was roughly alphabetized.

This female is younger than the one in 1800.  Is this a second (or third?) wife?  A different housekeeper?

Silas b. Marlborough; m. Jan. 25, 1772, Sarah, daughter of J.H. Herrington; removed to Westminster, Mass., and was a fifer in Capt. Noah Miles's Co., which marched for Cambridge in 1775.  In 1777 he was in the service at Bennington, Vt., and in 1780, he enlisted for three years.  He d. at Sempronius, Vt., 1815.  She d. at Brandon, Vt.  3 ch.

Sarah's father is Seth HARRINGTON.  Silas moved to Westminster before he married Sarah.  Sempronius is in NY, not VT.

p. 684	HARRINGTON. The earliest records of this name in New England have it Errington and Arrington.  The first of these forms soon received its aspirated prefix, making it Herrington, and this was the prevailing orthography for more than a century.  Robert Errington1, the immigrant, was one of the proprietors of Watertown in 1642.  He m. in 1649, Susannah George and had a son Thomas2, whose w., Rebecca Bemis, bore him George3, b. Aug. 1, 1695.  The latter m. Hepzibah, dau. of John and Abigail Fiske, whose sister was mother of John and Thomas Stearns of Nar. No. 2, and whose nieces were the wives of Samuel Hager and Stephen Sawin.  A cousin of Hepzibah m. Eliezer Bigelow.  So it appears that four of the oldest families in town were connected with each other by ties of blood relationship. 1. HERRINGTON, SETH4, was the 10th child of George and Hepzibah, b. Watertown, Sept. 15, 1729.  He is understood to have m. Sarah, dau. of Joshua and Grace (Bemis) Child, of whom mention has been made, coming here ab. 1750, possibly bef. m. took place.  They located on lot No. 23, now in possission of Ephraim Lufkin, which had been improved and built upon previously by Mrs. H.'s f.  She d. Sept. 30, 1759, leaving 4 chn., and he m. (2) Priscilla (Wilder), wid. of Benjamin Houghton of Lanc.  She had a dau., Priscilla Houghton, who d. Aug. 4, 1764, a. 5 yrs.  Seth Herrington d. Nov. 25, 1815, a. 86.  His w. d. the previous year, Jan. 28, 1814, a. 85.  He was afterward pub. to wid. Rebecca Temple, and prob. m. her a few months bef. his decease.  Chn.: 2.  SARAH5, b.

HOLT, SILAS, Westminster. Fifer, Capt. Noah Miles's co., which marched on the alarm of April 19, 1775, to Cambridge, and joined Col. Whitcom's regt.; service, 8½ days; also, Private, Capt. Manasseh Sawyer's co., Col. Dike's regt.; abstract for gun and blanket money dated Dorchester, Feb. 12, 1777; also, Capt. Elisha Jackson's co.; travel out and home (200 miles); service at 20 miles per day, 10 days, probably in Aug., 1777; company marched from Westminster to East Hoosuck under command of Maj. Ebenezer Bridge on an alarm at Bennington and was there dismissed; roll dated Aug. 27, 1777; also, Capt. Nathaniel Carter's co., Col Job Cushing's (Worcester Co.) regt.; enlisted Sept. 7, 1777; discharged Oct. 22, 1777; service, 1 mo. 24 days, at the Northward, including 8 days (160 miles) travel home; roll dated Leominster; also, receipt dated Westminster, June 4, 1781, for bounty paid said Holt by the town of Westminster to serve in the Continental service, as returned by Seth Washburn June 12 [?], 1781; Capt. Edgell's co., Col. Rand's regt.; age, 28 yrs.; stature, 5 ft. 8 in.; complexion, light; occupation, carpenter; engaged for town of Westminster; engaged Feb. 1, 1781; term, 3 years.

The "alarms" of 19 Apr 1775, raised by Paul Revere's famous midnight ride, were the Battles of Lexington and Concord — the "shot heard round the world."  If Silas was 28 years old when he was engaged on 1 Feb 1781, and his birthday was Apr 25th, then he was born in 1752, which makes a great deal more sense than later birthdates given for him.

p. vii	In each lineage is a Founder who arrived in one of the Colonies between May 13, 1607, and May 13, 1687, and a Patriot ancestor who gave military, civil service, or other aid in establishing American Independence in the period of 1775 to 1784.
p. 114	HOLT... Nicholas (1602-Jan. 30, 1685) m. .... Elizabeth Short MASS XV, 36; XVII, 47; XVIII, 89; XXI, 19, 20; XXIX, 375; XXX, 121, 162; XXXIII, 270... Silas (....-....) m. a. 1776 Sarah Harrington XXIX, 375

Obviously, Nicholas is our founder, Silas is our patriot, and the record we need is in vol. 29, p. 375.
