Hello JC,

I saw the Margaret J. BRIDSON with her Brother, William - but couldn't work out the family - well done !
I have gone the other way - so don't know if this below is right - I've gone by the Bridson & Kennaugh marriage in 1852, so Lynn has got it all to sort out.

From, IGI Extracted marriage record
JOHN KENNAUGH
Spouse: MARGARET JANE BRIDSON
Marriage: 06 JUL 1852 Malew, Isle Of Man

then searched the Census indices of Brian Lawsons - www.iomfhs.im/lawsons/LawsonBMD/census/census_index.html?Submit=Census+Indices

Can’t find Margaret J. Kennaugh after this 1891 Census.
So I went and traced her Husband, John Kennaugh and his Parents – back through the Census.
