Daughter 1 Kennedy of Bargany, (died young)

The best pedigree that I can find for the family of Kennedy of Bargany is in vol. 1 of James Paterson, History of the County of Ayr with a Genealogical Account of the Families of Ayrshire [1847] - available via Google Books and the Internet Archive. It says that Gilbert Kennedy and his wife (here called Janet) had a son Thomas who d. sp and two daughters who died young.
