Fantastic! I was pretty sure that Mary Chisholm was the wife of Richard Dawson Boyd, Sr. and you have confirmed it. I had also learned after my post about James although I only had the year of birth not the exact date. Thank you. This James went to New Zealand, I think. Is that correct? William was a new sibling to me.
Do you know the parents of Richard Dawson Boyd, Sr. who I think I found on familysearch as being born 1819 and died Aug 18, 1896? I have that Richard Dawson Boyd, Jr. was born 1853 and died between July and Sept 1886 which is possibly why his daughter Sarah administered Sr.'s estate.
Thanks
Peggy
