Hi. Their parents were James Mill b. 1824 St Vigeans & Ann Mill (nee Mill) b. 1823 also St Vigeans. James's parents were John & Janet Mill (nee Low), both of Arbroth who had daughters Mary (1816 ish), Anne Strachen (1828) & sons William Corsair (1830) & George (1833). Ann's parents were David & Agnes, there may have been another daughter Agnes. That's all I have. Does this tie in with any of your family?
