Please keep posting what you find about Richard and Mary Nichols. Could he have been the son of William Jr?,The same Richard which local lore finds pioneering western Pa.? Did word come out that his father was dying (1738), He could have come back and while there got married(1737). William, Hugh and Rachel Iams all appear to be born in westernPa./Md./Va. in the 1750's. Who were their parents? Keep in mind this land was the scene of the French & Indian War, and not really a part of any state'ssovereignty until Mason Dixon passed through after the war ended. Even then it was beyond the "Proclamation of 1763" line.
