Are too many sons being attributed to Peleg?

p. 49	FOURTH GENERATION... 38. PELEG CORBIN (Samuel, James, Clement), b. Sept. 7, 1749, at Woodstock; m. 1st, Lavinia (or Levina) Lyon, Jan. 14, 1773; she was b. Aug. 7, 1750, in Woodstock, the dau. of Nehemiah and Mehitable (Child) Lyon, granddau. of Ephraim and Priscilla (Harris) Child, and gr. granddau. of Benjamin and Grace (Morris) Child. (See Child Genealogy.)  She d. Nov. 18, 1788.  Peleg Corbin m., 2d, Rebecca Day of Oxford, May 26, 1789. He was a soldier in the Revolution, serving in the Lexington Alarm for four days, and elsewhere.  He was prominent in the organization of the town of Thompson, where he was an office-holder, school teacher, and member of the turnpike company.  He moved from Thompson to Woodstock about 1814.  He made a will May 6, 1811, which was filed April 2, 1816.  The births of all the children are recorded in the Woodstock Town Records. Children:         i.   PATTY, b. April 27, 1774; d. unm., Nov. 26, 1844.   111.   ii.   PRISCILLA, b. Dec. 30, 1776; m. Rensselaer Child.   112.   iii.   ELIAKIM LYON, b.

Note: Peleg is in the 1790 census of Thompson and the 1810 census of Oxford, MA, so did he move from Thompson to Oxford to Thompson to Woodstock?  It's most unfortunate that Peleg can't be found in the 1800 census.  The Lyon Memorial (see below) has the children born in Thompson.
