Hi,
I couldn't find ANY Crawfords in my transcriptions for 1861 or 1871 but found 1 for 1851 which is also on freecen.
http://www.freecen.org.uk/cgi/search.plPiece: SCT1851/113 Place: North Uist -Inverness-shire Enumeration District: 1
Civil Parish: N Uist Ecclesiastical Parish, Village or Island: Trumisgary

CRAWFORD Archibald Grnson U M 17 Ag Lab Inverness-shire - North Uist
This may be him prior to marriage?
There are quite a few on S/Uist

P.S. You may be better opening a new thread too for your query for more response where people will see the names first off rather than on here mixed in with others?
