Hi Paul,
I have Morrisons in Forgue & Huntly practically coming out of my ears if that's any help to you?
The furthest definite link back I have is William MORRISON, born at Brae of Bognie, Forgue in 1772 who married Isabel HENDERSON and died sometime before 1841. They had at least four sons - John, Alexander, William and George. George farmed at Mid Ashalloch, Forgue, until his death in 1883 and was married to Janet SIMPSON, although he also had two children by Janet TAYLOR. John maried Janet DAVIDSON, and William married Catherine BANNERMAN.
They were fruitful and multiplied, and I'm starting to think they're related to just about every Morrison in Forgue today!
