My McMillan family connection is as follows:-
James McMillan (died Scotland between 1841-1851) who married ? Mary Brown who died 1861 Scotland. In the 1841 census for Penninghame-Wigtownshire, Address: Newton Stewart they were both aged 70(born Ireland)
I believe they had a son Robert born abt 1801 who married Jean/Jane Grier; and two daughters Agnes born abt 1804 & Mary abt 1811.
If anyone has any of these folk in their family tree, or has more info on the family I would appreciate hearing from you.
