Julia, Sorry, I can't help you with info on your Hancocks on 1830 census, but thought it a huge coincidence. I am Gary Lay - got this email of yours from the Hancock List as I have been trying to work on my wife's genealogy - her maiden name: Karen Jo Hancock from Anderson, Indiana. The coincidence I refer to is that my Dad was from Casey County and my Mom lived in that area for a while and still has a few relatives there (her maiden name was Buis). I doubt if there is any relationship between your Hancocks and my wifes, but just thought it was interesting and thought I would drop you a note. Good luck with your search. Gary
