Jonathan Farr was styled the second in 1776. There were four adult Jonathan Farr's in the area at the time so they styled them 1st, 2nd, 3rd and 4th to avoid confusion on the tax records etc. and it had nothing to do with generation.
I found the original Estate files of Jonathan Farr 2nd on Ancestry.com dated 1972. His estate was administered by Jonathan Farr 3rd who would be his first cousin once removed. Jonathan Farr 3rd was noted on several pages of the estate files as "Jonathan Farr 3d now 2d". This proves that the numbers had nothing to do with generation. On the eighth page of the papers it mentions "Cash paid the deceaseds widow for the support and maintenance of one child under 7 years old from Feby 25th 1791 to March 20th 1793". This would lead one to believe that Jonathan Farr 2nd died abt Feb. 25, 1791. The child under 7 would be Charlotte Farr daughter of Rebecca/Robena the third wife of Jonathan Farr 2nd.
Jonathan sold his homestead Apr 27th, 1768 to Isaac Thomas. It was bounded on the East by the Ware River South by the land of Thomas Farr and west by the highway.
Marriage from the "Chesterfield, N.H. History" it only mentions of his wives that "there were 3 of them". Married Mary Wells 5 Jun 1751 (from Vital Records of Hardwick 974.43/H3, v2b) and had William and Jonathan in Hardwick. Jonathan's Great Grandson, Marshall H. Farr, went to Hamilton, Ontario and built railroads. Marshall's son, Herbert Marshall Farr, went from Hamilton to Hespeler, Ontario to start a factory making alpacca. Later he moved the factory to Holyoke, MA., he employed over 1,000 people. He married Annie Hespeler, daughter of Jacob Hespeler of Hespeler, Ontario. (from "The Farr Genealogy" by Rev. Charlese N. Sinnett)

FRENCH AND INDIAN WAR
DURING the French and Indian War, from 1755 to 1763, the town furnished soldiers for the army at Fort William Henry, Crown Point, Canada and Nova Scotia. Sometimes when the soldiers were leaving for the seat of war, services were held by the resident minister. Thus, on the 23rd of June 1755, Rev. Mr. Gardner preached at the desire of Capt. William Pierce, being the day he began his march with his company for Albany, in the expedition against Crown Point. Samuel Preston was a captain in the army in 1756. In Capt. Pierce's company, Michael Law was sergeant, John Law was corporal, Jonathan Farr was drummer, Nathan Whitney; Solomon Taylor, Josiah Wetherbee Jonathan Pierce of Stow, were privates. Ephraim Powers was sergeant in Capt. Preston's company, and Ezekiel Davis in another company. May 22, 1758, Ensign Jabez Brown and others of Stow, whose names are not known, started to join the army destined for Canada. In April, 1760; others started for Crown Point.
The following Stow soldiers went to Canada in 1760: Joshua Brown, Jonathan Far, Phineas Fuller, Amos Gates, Simon Gates; Abra Gates, Paul Graves, and Solomon Savcas, a servant of Mary Hapgood. None of the men were killed in the army during the war, but the following died while in service from diseases contracted in camp: January 4, 1756, Capt. Ephraim Brown, a few after his return from the army; July 23, 1758, Ebenezer Gates died at Lake George May 24; 1760, Abel Ray died at Shrewsbury, on his march to the army; November 1760, Isaac Taylor died at Crown Point; November 28, 1761, Stephen Houghton while returning from Crown Point. Robert Lawrence held a garrison a short time; was promoted Captain; was mortally wounded in an attack on the fort in 1690, by the French and Indians. Captain Thomas Lawrence, commander of a company, enlisted in the French War in 1758, from Pepperell and vicinity.
Jonathan Farr was a Revolutionary War Soldier also from New Hampshire. In Vol. XV of New Hampshire Rev. Rolls, reference is made to the service of Private Jonathan Farr who served under Capt. Kimball Carllon and Col. Moses Nichols, enlisted or marched from Chesterfield, N. H. in July 1777.
