Hi Jean,
Thank you once again for all your assistance with this query, it has been really appreciated. I do believe that it is probably the latter of your suggestions who is the William Crowe I seek. The likelihood of a second William Crowe, miner being off Island at the census time is probably remote. Thanks again Jean for all your detective work. My two brothers and I will be making our annual pilgrimage to the Island during TT week and will be visiting the Lonan parish/Laxey area with renewed interest in its history. We will be hopefully, do more research whilst there. Jean, you're a star!
