Note: There is a book called "The Fairweathers of Menmuir Parish, Forfarshire" by an Alexander Fairweather written in about 1874. A copy is at the Signet LIbrary, Edinburgh. Most of the data in this book is too general to be helpful for research purposes, especially as a great many Fairweathers had the sames forenames: Alexander, George, James and John on the male side and Elizabeth, Jean (or Jane)and Margaret on the female side.
