Thanks for those replies.
Annie, I was aware of that site. I only "discovered" it a few days before I left for Tasmania, and that was my first location I visited in Hobart. Luckily my photo's are a bit clearer than that shown on the website, and the inscription can be read.
Trish, the headstone is now located in a park which was once St.Andrews Cemetery, a Prebyterian Church. The headstones have been removed from the gravesites, and now line the perimeter of the park.
Matthew REID the convict arrived in Tasmania Aug 1836 from London.
Matthew REID the ancestor's wife died in NSW in 1843, and on her headstone she is described as "the relict of the late Matthew REID". There is no NSW record of Matthew REID's death. The wife died at Appin, where her daughter was living.
