Hi William, Sorry---I have so little info-cofirmed info is that Ellen Taggart married Robert Boyle 1877.
Ellen Boyle, daughter of Robert Boyle and Ellen Taggart(married Alexander Robinson 1915) she was my maternal grandmother, she told me that originally family came from Scotland. I was little more than a child--so never asked any more. I find I am trying to find Ellen Taggarts parents,and not finding much info or help out there. Thank you
