This is a long shot but I'm hitting stone walls so thought I might as well give it a try. My g.g.grandparents (William Duncan and Ann Innes) had 6 children. One of them was named Christian Catto Duncan. Now it seems to me that you wouldn't use Catto for a middle name unless it figured somewhere in the family line. So, does anyone have any record of Catto's marrying into Duncan or Innes lines? Unfortunately, I don't have any information on Ann Innes family.
