Hi, yes a visited the plaque when I was last in Glasgow (2017) its in what is known as the rose garden in Govan. Just behind the Police station. It looks like the graves were transferred and the headstones placed around the garden wall. It's in a bit of a sorry state, the garden that is, in fact, most cemeteries are. I found used syringe needles and beer cans in the bushes. Glasgow is somewhat poor since the ship and steel making is gone. I think the population has declined from 1.2M to about 600k now.
