The fact there are 3 conflicing Y haplogroups attached, it gives rise to these connections. On Ancestry, this James Richard McDonald only has one wife connected and it's not Margaret Greer. All the trees on there show:
Father
Edward T McDonald* (1761–1835)
Mother
Mary Rowland* (1764–1814)
Spouse
Katherine Keturah "Kitty" Jones* (1801–1890)
Married 1820
So I'm wondering if Margaret Greer and her family aren't perhaps connected to the wrong McDonald family. That would explain some of the haplogroup conflicts.
