I'm so glad you found this old message! My husband is the great grandson of Charles. His grandfather was Hugh MacPherson. A few years ago I made contact on this list with another great grand daughter; her grandfather was James MacPherson. This is so exciting!
Please contact me at firstname.lastname@example.org so I can send you what I have on the family. Most of my work was on the ancestors, because my mother-in-law hadn't kept in touch with the family after about 1960. James' grand daughter had much more info on the descendants.
My first question will be: Do you have a date of death for Marion Smith MacPherson? I only know that she died sometime before 1955 and have never found gravesites for either of them.
