William MUIRHEAD, millwright m Isabella DUNN. I have just gotten the death certificate of their daughter Isabella c 1788 - 1869 in Barhead. She m 1827 in Denny to Thomas SMELLIE [an ancestor of mine through his 1st wife, Jean AGUR]. They had two sons that I know of, George & William. Wm MUIRHEAD & Isabella DUNN do not appear in the OPRs at all, does anyone know anything about this couple? Regards, Don McArthur.
