I did a quick survey of my records for the surname Champ/Champe. The following appear in the 1850 Censu, which you can view online:
There is a A. Champe and Margaret Champe in the Cemeteries of Brown County book.
There is a Mary Champ in the 1870 Census
These are in the 1880 census, also which you can view online:
I have also added you to the researchers list in the surnames section under Champ/Champe.
