The 1911 Census noted a number of Hurley families living in Kildeema North townland in Annagh Electoral divisioin in County Clare. Annagh is one of the Ellectoral divisions which is associated with Miltown Malbay.
It is possible that William's father was at House No. 10. The link is here: http://www.census.nationalarchives.ie/pages/1911/Clare/Annagh/Kildeema__North/357695/
If you have traced him and know his parents names, you should be able to find further information about the family through the Clare Library website. The link to view the records associated with the civil parish of Kilfarboy is here: http://www.clarelibrary.ie/eolas/coclare/places/kilfarboy.htm
You can also access his civil birth record online through Irish Genealogy.
Please let me know if you need further assistance and I will do my best to help.
All the best,
