Little is known about Christiana Smart other than she was married to
John Gallon and that she is recorded as the mother of two children. Two others, including Margaret are attributed to her. There appears to be no evidence for where she lived, where she was married to John Gallon, or when and where she died.
The given name "Christiana," or the variation Christina, appears twice in her possible grandchildren, including a daughter of Margaret Gallon and John Thompson.
The name "Smart" also appears, curiously, as the middle name of a John Jaffry who appears as the father of a child in the St. Andrew's Anglican church register of New Carlisle in 1848.
As always, any other clues or evidence is greatly appreciated.
