Thanks for all that, Steve! I had no idea that soldiers were recorded in such detail. I didn't know that their pay would be docked for the food they got in hospital - thanks Ken - but I suppose I should have known. Even now, the army tracks every penny handed over to soldiers, and is very concerned that you should never get a single cent more than your entitlement.
The fact that Grampa Jim was in St. John in January/February 1854 is probably a good indication that his son Matthew was born there, rather than in Halifax, as he appears to have thought. I appreciate all the information, Steve, and I would be delighted to have anything else you care to look up, but I don't want to presume upon your good nature. (If you do find anything else, perhaps a PM would be easier than multiple posts?)
Thanks again.
