Hello

I think that Coltburn is near to Muirkirk.I too think that David Gorman, father of Isabella's son, David, was a distant family member but I have been unable to find him. I have been researching this line since my husband is a descendent of David Gorman Robertson.You may know this but on David Gorman Robertson's marriage certificate, 17th February 1899, to Jessie Maca McIntyre, David Gorman is listed as father, but is marked deceased.

I am not sure who Catherine Gorman is either.

John Miller Armour is interesting as he goes on to remarry after Isabella's death.
