Are there maps which would relate to a census?
I'm thinking in terms of adjacent area search in a census. Say the family said a person grew up in Morganfield, Union Co., Kentucky. Your search doesn't find him there. Where do you look next?
On the Kentucky site of Genealogy Wise, someone mentioned the tri-couny area of Henderson, Union, and Webster co; so now I know how to extend my search. But a 1900 map of Kentucky might also tell me the names of the adjacent Illinois (and Indiana?) counties across the Ohio river.
Do such maps exist? Where do we find them? Are they online?
