Hi Sharon
The 1901 census has William O Clazy living in Duchal St Curse,Kilmalcolm (Ref - 569 ED 2 Page 15)
William O Clazy, 30, writer, b. Paisley
Robina B Clazy,sister, 32, b. -do-
Harriet R Irvine, servant, 27, b. Leith
It doesn't look as if he married to 1901. You would get the full info from his death cert that can be viewed online at
www.scotlandspeople.gov.ukWilliam Oliver Clazy died in Blytheswood RD, Glasgow, 1906, aged 35.
Robert Smith Clazy (b. 1869) married Helen Mary M Wilson, Edinburgh, St Giles in 1931. You can get the cert in the same way from Scotlands People
