Perhaps the later generation Francis McDonald that Chantell is following is Francis Greer McDonald (b. 1856), son of Charles McaDonald and his wife Rebecca. Charles was a son of Francis McDonald and Nancy Greer.
The Children I have found for Francis McDonald and Nancy Greer are as follows: Charles b. 1824, Greer b. 1826, and George b. 1830-10-27.
The children I have for Greer McDonald and Elizabeth Bedal are: Albert b. 1847, Alice b. 1848, Helen b. 1850.
Hope this helps.
