I just wanted to point out that ancestry.com acquired the 1973-1999 Kentucky Marriages database from the Kentucky Department of Libraries & Archives already indexed electronically. I have verified at least ten marriages for my family that are incorrectly indexed to the WRONG COUNTY.
If you are looking for missing relatives--TRY McCREARY COUNTY RECORDS. My living cousins & uncles are incorrectly indexed over there instead of in Martin County--where they married.
Another clue that the database is indexed incorrectly? There are 378 marriage records for the surname Preece in McCreary County, Kentucky from the 1973-1999 Kentucky Marriages database BUT there is not a single Kentucky Death Index nor Social Security Death Index listing for the surname Preece in McCreary County.
