Hi Ann
No, you can't view Jane Craine nee Teare's will online. If you don't live on the IOM, you can view it on film at a Church of Jesus Christ of Latter-Day Saints, Family History Centre near where you live. I've never actually done this myself, so if you're not sure how to go about it, I'll direct you to a string of messages headed "Enquiry about films" which were posted in July 2010. Use the search facility (I've tried various combinations to bring this thread up, including using the subject heading which didn't work.) The way I found it was by typing KayN. This produced 26 results. About the 7th in the list is the "Enquiry about films" thread.
