hi Karen, here is a list of everyone buried at Mount Street Cemetery (up to 2012), that I compiled exactly 6 years ago. At date of writing there about 1100 burials but they estimate hundreds more and unfortunately, I haven't done an update for years. However your Connell are on there.

The earliest surviving grave marker dates from 1851 and the latest from 1954, although only around 200 headstones survive. Many of the early markers were simple wooden crosses, which have long since vanished and so there is little or no information where most of them are buried exactly
