Hello, All, In the Perthshire Military Certifications 1802-1810, I have found a Peter Thomson, wife Isobel Pirie, Caputh parish with 2 children under 10 as of 1804. He was a member of the 4th Battalion 1st Brigade Royal Perthshire Volunteers. I am able to access record PE66 from the computer, but a note directs me to see also PE/25A which I cannot. This family may be my ggg grandparents as the number of children and timing are compatible, however my ggggrandmother was an Isabella Pirnie not Pirie. Would anyone be able to check PE/25A to see if that record might shed further light? Thanks, Barb in snowy Canada
