where was Vina McKinney born in the U.S. in 1800's

I see that 'late 1800's' refers to the period between 1870 and 1900.  Have you found her on the 1870 census?  Is McKinney a maiden or married name?  The 1870 census shows using an exact match one person in Carter KY but born in 1805 in Virginia.  https://www.familysearch.org/search/record/results?count=20&q.givenName=Vina&q.givenName.exact=on&q.surname=McKinney&q.surname.exact=on&f.collectionId=1438024  If I don't use exact match names, I see 340 hits.  If I use the 1900 census, exact matches...  I get 681 hits.

Maiden Name.  How would I pull up the 1900 census. Thank you very much

Randy, I used FamilySearch.org... registration needed but it's free.  Asking for Vina McKinney (exact),, and filtered by the 1900 Census.  I see 3 results.  www.familysearch.org/.../results
