Union Baptist Cemetery in Cincinnati, OH
Colored American Cemetery (now called United American Cemetery) on Duck Creek Rd in Cincinnati, OH
Mary E. Smith African American Cemetery in Elsmere, Kentucky.

Can you help me locate records so I can find the exact grave location? What happens to records for these older cemeteries?"

Linda,

You might try the Genealogy Dept. of Hamilton County Public Library - Main Branch in Cincinnati, Ohio.

A great research person there is Mr. Dennis Day. Mr Day is very well versed on AA History of the Cincinnati & Hamilton county area and he may be better able to answer your questions. I attended a session at that Libray on AA Burial Records in Cincinnati & Hamilton County presented by Mr. Day.
