I have an entire family in the works that traveled in the largest wagon train of the time, 1851, to the Willamette Valley, Oregon on the Oregon Trail. It's the "Keeney Wagon Train". I didn't see other wagon trains, but wondered if this is a good category. Many people besides the Keeney family and relatives traveled in it; so there would be other surnames too. The matriarch, whose sons led the train, involved is Burkhalter-179.
