I've found John Maxton (son of Thomas) christened Jan 1731, Dunbarney -- which is just east of Forteviot -- Trinity Gask a few miles to the west. The three parishes probably touched. Another JM baptised Feb 1730, (Falkland - 20 miles or so) son of another JM. I tried to post a text file of the Maxton Parish registers, 1645-1745 to this box yesterday, but no luck. I've e-mailed it to George asked him to send it on to you, but I'm sure folk would appreciate if someone could work out how to post it and keep the formatting intact, or turn it into a database.
