I don't know if this is a clue it came up in the results you sent
Signature of the lands of Kippens granted to Mungo Haldane (Hadden, Haldan, Halden, Haldin). 16 Oct 1673
Signature of the lands of Carbeth etc granted to John Haldane and Mungo Haldane (Hadden, Haldan, Halden, Haldin). 22 Apr 1708
The baptism of another daughter Jannet Haddan in 1708 is done at Kippen.
The name Hadden is being used, also so Mungo died 1686 and lands are granted to his son John and a Mungo Haldane, a brother?
