Thank you! "Margaret" is not a name I usually think of as an alternative to "Mary."
I have her death as 08 Feb 1874 according to PANS. Still looking for her burial place. I have not found any info on her husband, David Archibald, death date or burial.
Now on to look for the mysterious father of Mary/Margaret. There are a gazillion Henry Bulyea/Belyea and not a one married to a "Rachel." The search continues!
Thank you so very much for your help, Marie!
