Deacon John Leavitt (1608–1691) was a tailor, public officeholder, and founding deacon of Old Ship Church in Hingham, Plymouth County, Massachusetts, the only remaining 17th-century Puritan meeting house in America and the oldest church in continuous ecclesiastical use in the United States. Hingham's Leavitt Street is named for the early settler, whose descendants have lived in Hingham for centuries.
Leavitt was born in 1608 in England, but his exact birthplace is uncertain. Leavitt first appears in the annals of the Massachusetts Bay Colony in 1634, when he is shown in records of Dorchester, Massachusetts, as having been granted a house lot. Within two years, the early settler had moved to nearby Hingham, where he was granted land in 1636. In his early history of Hingham, attorney Solomon Lincoln recited the oft-told tale of Leavitt's supposed origins:
"The family tradition concerning John Leavitt is that he was an indented apprentice in England," wrote Lincoln in 1827, "and that he absconded from his master and came to this country when nineteen years of age.... He received a grant of land in this town in 1636. His homestead was in Leavitt-street, recently so named, on both sides of the river."
In the same year, Leavitt took the Freeman's Oath of the Massachusetts Bay Colony. In records on file at Boston Leavitt is shown on March 3, 1636, as pledging loyalty to the English Crown. In the early Massachusetts record the early English settler is listed as John Levett, as the tailor apparently spelled his own name for several decades, until it became corrupted later in life.
