The Mortimer Cemetery, Liberty Street, off Main, Street, Middletown, Middlesex, Ct, has never been online as far as I know. I obtained this enumeration from the Godfrey Lirary in Middletown (which is a treasure trove!), and have transcribed it.
The search engine I put on this site isn't very effective. You'd be better off using the one in your browser. All the "same-surname" stones are not necessarily in one area of the cemetery, so click until you find all of them.
Hope this helps someone!
