Wow - that would be fantastic, Emms! Thanks very much for the offer. I live in the south and can't head Thursby way for some time. If you have the spare time and it isn't too much trouble, confirmation that a headstone exists would be fabulous. Robert Jackson was born around 1750 in Lanarkshire, Scotland (although some accounts say it was Dumfriesshire); he was an army medical reformer and inspector general of hospitals.
Best wishes
