you don't mention what year the census was in which you found the reference to Clare.
The Clare Library has an outstanding on-line (and best of all - FREE) genealogy & family history website. Go to www.clarelibrary.ie
and select 'genealogy & family history'. Also try the Clare Past Forum accessible through the same website. It is full of very knowledgeable & helpful people with lots of local knowledge.
If you are on Facebook, there is a Clare Genealogy Group which could also be helpful.
The CLare Library is not associated with the CLare Heritage & Genealogical Centre, which is a profit making organisation who do commissioned research only. They have no records available to the public.
