The surname Garrett was baptismal name "the son of Gerard". The name was derived from the Old German Gerhard - meaning spear-brave. The name was brought to England in the wake of the Norman Conquest of 1066. The name has numerous variant spelling which include Garrit, Garred, Gerrett, Geratt, Jarrett, Jarred, Jarad, Garrould and Garrod to name a few. Early records of the name mention Gerordus (without surname) listed in the Domedays Book of 1086. Hugo Gerard was recorded in 1199 in Northumberland. William Gerart was documented in 1281 in the County of Suffolk. Johannes Gerard of Yorkshire, was listed in the Yorkshire Poll Tax of 1379. Thomas Garard registered at Oxford University in 1511. Garit Pender was buried at Cheadle Church, Cheshire in 1678, Garrat Cocke (gentleman) was buried at Newcastle-on-Tyne in 1637. William Garret was buried in the Town of Chesham, Buckingham County 1381. Associated arms are recorded at Burkes General Armory and Ulster King of Arms.

Abigail Lawry was born on 28 Jun 1782 in Provincetown, Barnstable Co., Massachusetts. She appeared on the census in 1850 in Vinalhaven, Waldo Co., Maine age 69, and the census in 1860 in Vinalhaven, Knox Co., Maine, age 79, originating from Massachusetts. She died on 28 Mar 1862 in Vinalhaven, Knox Co., Maine. "Lawry Families..." has 1859. She was also known as Nabby Larry.  

The only Abigail listed in the Provincetown VRs was born to John Larry and Abigail on 29 Jun 1790.  If she were the 1790 Abigail, then the census data is wrong. I don't think there'd be a 10 year discrepancy there though especially with it being consistent in more than one census. If she were a daughter of John and Abigail, her mother would have been only 12 years old when she gave birth. I believe she is a later, undocumented, daughter of John and Betty (Kilborn) Larry or she may have been previously been married to a Lawry/Larry and the marriage to Truman Garrett may be hers and his 2nd marriage. This assumption would be based on age at marriage. One other consideration, she and Truman live next to the Bartons and Larrys in the 1850 census.
