I just noticed that my "d.1705" taken from the year of her will is probably wrong, and the will (1705) looks indexed wrongly, in view of this burial:
CORKILL, Margaret Braddan 9 Apr 1707 CURLET.

LDS film no.0106209 covers the years 1705-1710, so perhaps Shirley took the first year from the film box, or perhaps it was put under 1705 when the wills were filmed.

Margaret Corkill's will is recorded as: CORKIL, Margaret 1705 Braddan A 18 0106209.
I see that the will (Arch., no.17) which looks as though it is immediately before her one in the volume is dated 1706 yet is also in the index under 1705:
COWLE, Isable 1705 Braddan CHRISTIAN A 17 0106209.
Her burial: COWLE, Isabell Braddan 10 Aug 1706 CHRISTIAN.
