Just now saw posting, as am researching Schardein Cemetery.
A contact for Schardein Cemetery is Dr. Phil DiBlasi, forensic anthropologist at the University of Louisville. His office maintains any existing burial records for Schardein and Eastern Cemeteries. You can contact him either by phone or email, he will need full name, date of birth, date of death for whomever you are looking for. He will review the records and send copies of any information he has in his records. While I'm not sure if he provides them through email, he does provide copies via regular mail, and will need a mailing address, he doesn't charge for sending the info.
His phone number is: 502-852-6724. His email is: firstname.lastname@example.org
