Hi Ray
I know its years since you posted this, but I have an article about a Logie Coldstone Anderson, published in from 1904, that might be of interest to you. It refers to events that took place in the 1700s around Logie Coldstone area.
If it would be of interest to you (it's too large to paste into one message) , please get in touch and I will email it to you, or to anyone else related to any Anderson, Duguid, Gordon or Farquharson families from the Logie Coldstone area.
