Pennsylvania's leading fur traders. A key to his success was establishing trading posts in Native American villages, as the French traders did, and learning their languages and customs. At the time, the usual British practice was to set up a post at a site for their own convenience, generally at a major crossroads, and wait for Native Americans to come to them. Croghan learned at least two Native languages, Delaware (an Algonquian language common to the Lenape of the mid-Atlantic region) and probably Seneca (an Iroquoian language spoken by the westernmost Seneca nation of the Iroquois), whose territory extended into what colonists called Pennsylvania. They also had hunting grounds in the Ohio Valley. These were the languages of the two major nations of Native Americans in the region. Croghan also learned Native American customs, rapidly adopting the practice of exchanging gifts when he met with the people. He established his first trading base and wintered in a mostly Seneca village at the mouth of the Cuyahoga River on Lake Erie. (This area later developed as Cleveland, Ohio.) During the early years, Croghan's primary business partner was William Trent, also a trader. The son of the founder of Trenton, New Jersey, Trent likely supplied capital to acquire trade goods and set up their business. Marriages and families Croghan married in the 1740s and had a daughter, Susannah Croghan. He later married again, while serving as Deputy Indian agent to Sir William Johnson, British Superintendent of Indian Affairs in the Northern District. His second wife was a Mohawk woman, Catherine (Takarihoga), daughter of Mohawk chief Nickus Peters (Karaghaigdatie). Their daughter Catherine (Adonwentishon) Croghan (1759-1837) would assume her mother's hereditary role as head of the Turtle clan. She later was the third wife of Joseph Brant, the prominent Mohawk war leader who led his people during their migration and settlement in Canada on lands granted by the Crown after the American Revolutionary War. Brant's sister Molly was a long-term consort of Sir William Johnson, so Croghan was doubly connected to influential British and Mohawk families in the East. Elizabeth Brant, a daughter of Joseph Brant and Catherine (Adonwentishon) Crogan, married William Johnson Kerr, a grandson of Sir William Johnson and Molly Brant. King George's War, 1744–1748 Britain's blockade of French ports made the few French trade goods reaching Ohio Country prohibitively expensive; this resulted in a bonanza for the Pennsylvania British traders that
