Hi Tim,
I attach a record of Griffith's Valuations taken c1850. There are a number of Connor/Connors in the townland. No William recorded.
Where did Elizabeth die. You may find that on www.irishgenealogy.ie - Free site.
I sugges that you write to the Letters Editor of the Clare Champion - clarechampion.ie - and request that he print details of your request.
Include your email address and telephone number.
Regards,
