Hi Andrea, thanks for the reply.
I've heard of "dressed stones" which I always took to mean sculpted flat/smooth, but if that was what it meant in the Interment Records, then what would the difference be between a "Private" Lair (possibly with a dressed headstone) and a "Dressed" Lair?
I was wondering if it related more to the ground itself eg. dressed with some kind of 'surface' (eg. grass which gets mowed and maintained). Whereas perhaps "Common" means a plot with multiple burials where the groundsmen don't even maintain it - its "un-dressed" ground perhaps and just grows wild??
Either way, I supposed "Dressed" and "Common" are pretty much the same thing nowadays ie. unmarked. And if Glasgow City Council are anything to go by, very probably neither are maintained and just grow wild!
