George Galphin became a highly respected trader among the
Lower Creek tribes in the Georgia and South Carolina region within a few years of arriving in America.
Adair praised his skill in negotiating with the Creek to stay neutral during the French and Indian Wars (1760–1761). Eventually he came to own the
Silver Bluff trading post. In the 1760s he was involved in a project with fellow trader John Rae encouraging Irish immigration to the region. On the Georgia side of the
Savannah River, these immigrants were encouraged to move onto a tract of land called Queensborough. ==Revolutionary War service==
