Patrick Mckenna 1851 census?

[wildgoose]

can any one help me find Patrick McKENNA & wife on the 1851 Census.  Tried Scotland's People without luck.  I do have an OPR Proclamation Banns & Marriages which recs.
1850, June 23rd, 30th & July 7th, Linlithgow, WLN
Patrick McKENNA, labourer, res. Linlithgow, b. County Tyrone
Father Patrick McKENNA, labourer. 
Susan KERDLE, res. Linlithgow, b. County Cavan. 
Banns proclaimed, 23rd, 30th June & 7th July.   

His first child James was born in Linlithgow in 1852.  later children record place of marriage as Falkirk but neither Pat or Susan appear on the 1851 in stirling.  Like most Irish ancestors it's a bit like juggling with jelly.
