I believe I am a descendant of Joseph Prior (1796-1851) and Amelie McCamant of Osage County Missouri. I visited his grave there, but my photos are too dark to use.
Their grandson Joseph Francis Pryor (1867-1927) seems to have changed his surname spelling on his way West, where he farmed in Washington, Oregon, and California.
Because of this spelling issue, I would like to connect or disconnect this Prior from those associated with Pryor's mill (spelling from my sources) on the Gasconnade river. They also came from Ohio. I started searching land records in the county seat of Linn, but have put it aside.
I'd be happy to exchange further information and sources with anyone.
