Luke and Rebecca are indeed buried in Clinton Co. Indiana at Shiloh cemetery near Colfax, In.(Highway #52). They are in the census for Clinton Co. in 1840 & 1850. Luke remarried when Rebecca died. He died in 1854. Many of their children are from the Colfax area also.Some of the children went to Hoopston Ill.I am a descendant of son Greenberry Blacker who lived near the Boone Co. Line. I have some birth & death dates to share.
