After a few brief stops in Massachusetts the Philbrick family settled in the New Hampshire town of Hampton. James was a mariner by trade. The waters of coastal New Hampshire were akin to today's highways, bringing exports, especially wood products such as pipe staves and masts for ships, to the larger ports in exchange for English imports of cloth and other goods. In addition to working on the water, James farmed, buying marsh land in 1650 with his brother Thomas Jr. The rich marsh salt grass was cut and used as fodder for cattle.

It was once believed that Bethia Philbrick who married Caleb Perkins in 1677 was also a child of James and Anna.  The Hampton Lane Memorial Library genealogy site does not include her as a child. Her profile on the genealogy site WikiTree also disputes her parentage and lays out a compelling case for her to be the daughter of Thomas Jr.  Thomas and his wife are recorded as being the parents of Bathia Philbrick how was born on 15 December 1654.
James died on 16 November 1674, he drowned along with another man in the Hampton River.  His widow Anna probated his estate. The following year she married widower William Marston on 5 July 1675. Between them they had 15 children.
