Hi Donna,
The marriage was in Braddan, so I don't have the details. IGI says 14 Feb.1861.
The 1881 census has:
Evan KENNISH Head M Male 57 Maughold, Isle of Man, Farmer of 15 Acres
Margaret KENNISH Wife M Female 43 Maughold, Isle of Man.

So her age there looks like d/o William Kissack and Margaret Morrison, but there are no further details in the par reg., nor for the marriage of William Kissack and Margaret Morrison on 10 June 1837 [details of fathers etc given only from 1849 onwards].
