Henry Willard's birth is recorded in the records of Concord, Middlesex, Massachusetts, as follows: "henary Sonne of mair simon willard & mary his wife borne ye 4h June. 1655."
He married twice. When Henry contracted to marry Mary Lakin, his father gave him one quarter of the farm at "Nonacoaicas." "Whereas, upon a contract between my son Henry Willard and Mary Lakin, daughter of sergeant Jno. Lakin, both of Groton, I thought it meet to settle something upon him for his outward subsistence...." dated 16 July 1674 They were married 18 July 1674.
Henry and Mary lived at the Nonacoicus Farm, his father gave him, upon his marriage. He was still living in Groton in 1684-5, but probably removed to Still
River Farm on the Still River in Lancaster (later town of Harvard) two years later. In a rate list of 1688 was the name of Henry Willard and his younger brothers, Benjamin and Jonathan, and others.
Henry married Dorcas Cutler at Lancaster in 1689. Anderson does not give a maiden name for Dorcas, stating that only secondary sources identify Dorcas as a Cutler and that there is no evidence for this identification.
Henry died in 1701. His Will is dated August 24, 1700, and it was attested to in court on August 8, 1701. "The last will and testament of Henry Willard, Sen of ye Towne of Lancaster in ye county of Middlesex in ye Province of Massachusetts Bay in New England....."in it he mentions oldest son Henry, 2nd son Simon, eldest daughter Mary, John his 3rd son, Hezekiah and Joseph (not yet 18), daughter Sarah (unmarried), his beloved wife Dorcas and the rest of his children Samuell, James, Josiah, Abigail, Jonathan, & Susanna.
27 Aug 1726 Lancaster, Worcester, Massachusetts, USA, is frequently seen in trees as a death date, including some SAR Applications But it was clearly his will proved in court in 1701. John Willard husband of Mary died 27 Aug 1726, not Henry.

However, there are no known yDNA or mtDNA test-takers in his direct paternal or maternal line.
It is likely that these autosomal DNA test-takers will share DNA with Henry:
