There were 11 Kemper/Campers listed in the 1800 census of Kentucky.To my knowledge, nothing has ever been published that identifies all 11.I have taken a close look at these individuals and, in my judgement, I believe they are all included in the Willis Kemper 1899 book.What follows is a listing I have compiled of these individuals with their reference numbers from Willis' book.
Lettice Camper (Fayette Co) - Lettitia Whitesides the wife of Henry no. 21, the son of John and Alice Utterbach Kemper.
John Kemper, Jr.(Garrard Co) - No. 104. He is son of Henry and Lettitia Whitesides Kemper.He is likely call "Jr." because he is the younger of the two Kempers.
William Kemper (Montgomery Co) - No. 105 and also a son of Henry and Lettitia.
Ruben Camper (Montgomery Co) - No. 106 is also Henry and Lettitia's son.
Henry Camper (Fayette Co) - No. 107 is also Henry and Lettitia's son.
John Kemper, Sr. (Garrard Co) - No. 48. Son of John Peter and Elizabeth Fishbach Kemper.
Enoch Kemper (Garrard Co) - No. 132.Son of John and Sarah Rosser Kemper
William Kemper (Garrard Co) - No. 128.Also son of John and Sarah Rosser Kemper.
Tilman Camper (Fayette Co) - No. 73.Son of John II and Ann Weaver Kemper.
Caleb Camper (Harrison Co) - No. 157.Son of James and Judith Hathaway Kemper.
Joel Camper (Henry Co) - No. 210.Son of Peter and Mary Whitesides Kemper.
I would be interested in knowing if anyone has come across such a list before.If there is interest I may be able to add some more info to the above.As genealogy is always a "work in progress" I welcome corrections and comments.
