Francis William Pettygrove (1812 – October 5, 1887) was a pioneer and one of the founders of the cities of Portland, Oregon, and Port Townsend, Washington. Born in Maine, he re-located to the Oregon Country in 1843 to establish a store in Oregon City. Later that year he paid $50 for half of a land claim on which he and Asa Lovejoy laid out a town named Portland after the port city in Pettygrove's home state. Lovejoy preferred Boston, but Pettygrove won a coin toss giving him the right to choose the name. Teamed with Benjamin Stark, who bought Lovejoy's half-interest in the town site in 1845, Pettygrove engaged in a highly profitable three-cornered trade between Portland, San Francisco, and Hawaii. Making money in his stores and warehouses, in trades of lumber, grain, and salted fish, and in real-estate deals, Pettygrove by 1848 was one of the richest men in the Oregon Territory. When the California Gold Rush drew potential laborers from Oregon and threatened Pettygrove's short-term prospects, he sold his assets in Portland and vicinity. In 1851 he joined with others to start a new town, Port Townsend, on Puget Sound in what became the U.S. state of Washington. He died at the age of 75 and was buried in Port Townsend. Pettygrove was married to Sophia Roland, with whom he had at least two children, one of whom was named after Benjamin Stark. While living in Oregon, he belonged to the Pioneer Lyceum and Literary Club of Oregon City and served as jury foreman in a trial there related to the Cayuse War. Pettygrove Park in southwest Portland and Pettygrove Street in northwest Portland are named after him. (Wikipedia).
