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 Library 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!
Also:Scroll down to the bottom of the page and click on the LINK to the 4-surname-site, which is a huge repository of New England vital statistics.From that site, you may also want to access the Genealogical Gleanings Award page, with the best websites (being added to on a regular basis) for New Eng resources. as well as a few in the mid-west.
