Marriage look up - Brisland - Londonderry

[Campbell21]

Hi
I wonder if someone can help me I am trying to find the marriage of Patrick Brisland to Margaret they had the following children Catherine, Mary Ann and William in the 1800's when William married in 1897 they lived in Campsie Londonderry and Patrick was a farmer.  If there is any census or other details that people can help me find Patrick.

I am not sure why but Patrick is not buried with his wife & children in Faughanvale cemetry so if anyone could help with this I would be really grateful. 
Thanks Campbell21

PRONI Will extracts- Margaret Brisland, widow, Campsie died 25 Dec.1887, son William mentioned.

First complete census for Ireland is 1901.

Civil registration of Catholic marriages began 1864 (from 1845 for other marriages).

Griffith's Valuation (mid 1800s)- couldn't see your Brislands but you could try searching for them and maybe you'll spot them:
