He married Elisabeth Baker, 5 September 1751, in Newbury, Essex County, Massachusetts.(1272) It isn't certain that this is the Joseph who married on that date, but there appears no other Joseph Wallingford who is a likely candidate.
Elisabeth was the daughter of John Baker. No records for the deaths of Jonas or Elisabeth can be found in the published Essex County, Mass. vital records.
He was baptized 22 March 1729/30 in Newbury, Essex County, Massachusetts.(1273) On 14 March 1742/3 guardianship of Joseph, Samuel and Benjamin Wallingford, all minors under 14 years of age and children of Samuel Wallingford late of Rowley, was granted to Samuel Jewett of Rowley. Samuel was their stepfather.(1274)
On 13 October 1746 Joseph's mother, the widow Lydia Jewett, gave bond with William Fisk and Daniel Tenney, both of Rowley, for guardianship of Joseph, a minor upward of 14 years of age.(1275)
On 8 April 1751 Joseph "Recd of my mother Mrs. Lydia Jewett who was Guardian for me During my minority the whole of my proportionable Part of ye personal Estate of my father Saml Wallingford late of Rowley Decd Intestate..."(1276) On the same day Joseph, a yeoman of Rowley, gave bond with Richard Stewart, Rowley, and John Sargent of Newbury, gave bond for guardianship of his brother Samuel Wallingford, a minor upward of 14 years of age, witnessed by James Tarbox. Richard Stewart was awarded guardianship.(1277)
He served in the Massachusetts Militia in Col. John Greenleaf's regiment, Major Joseph Gerrish's company from 18 January to 12 September 1754. The name of Joseph Wallingford was listed twice on the muster roll, which is either a mistake or there was another Joseph in the company, who is as yet unaccounted for.(1278)
Administration of the estate of Joseph Wallingford "late of Newbury", deceased intestate, was granted to his widow Elizabeth on 18 April 1757. This record actually said he was late of Newbury, but all other probate records state Rowley so it was likely a error in the original record(1279). An inventory was taken on 4 May 1757 by Daniel Giddinge, William Caldwell and Abraham Brown. In addition to household goods there was a "homestead containing about six Acres Consisting of pasture tillage Orchard & Swamp with the Easterly End of a small Dwelling house and two thirds a [sic] small barn" valued at £20. There was also an acre and a half of out lands worth £2. The total estate was valued at £28 13s 5p.(1280)
In the account of the widow Elizabeth, taken on 9 May 1760, is a listing of various debts paid, two of which indicate that they had a child. One payment was to "Sarah Baker for Nursing" while another was to "Anthony Lony [possibly Lory?] for Child's grave".(1281)
Joseph Wallingford and Elisabeth Baker had the following child:
255 i. Child5 Wallingford. Child died before 9 May 1760, probably in Rowley, Mass..(1282)
