I was wondering if there was a Cox connection...
Samuel's father Daniel reportedly came to Jackson Co MO 1836-1837 from near Danville, Mercer Co, KY (now Boyle Co Ky). Samuel was born in Mercer Co KY. Daniel Crump is found in the 1840 census of Jackson Co Missouri so I suspect that the Samuel Crump/Paulina Cox marriage did infact occur in Jackson Co MO.
FWIW
