Lodger, I really appreciate your help on this.
I always knew it was a long shot, with Thomas snr injured down the pit and then dying, and James, the elder boy, losing his hand in an accident the chances of money for gravestones was always highly unlikely.
James, my great grandfather, grew up to be a respected city missionary in Brickfield Open, Sydney Place / East Campbell Street, and I reckon managing that from losing a hand as a child in Airdrie is a good enough memorial.
The frustration is just not being able to find out where Thomas snr came from - the churchyard was always going to be a vain hope. I can only assume poor little Thomas, age 7, just had a pauper's grave, and just hope it was near his father's.
Thanks again, and good luck to everyone else who is still trying to search there, beginning to sound as if Joni Mitchell was quite prophetic
