I continue searching for Alexander Matheson (b 1806) and married Jean Munro (b about 1811) of Creich. Their children were:
John (b 1831); my ggrandfather who married Ellen Caldow in Ayrshire in 1869.
Margaret (b about 1834)
Angus (b about 1837)
Christy (b about 1841)
I think Alexander's parents may have been John Matheson and Marion McKay of Torboll but I have no prove to substantiate this.
If anyone has information about this family please contact me.
