Will summaries are on www.manxnotebook.com, an index by Brian lawson is on www.iomfhs.im which gives the mormon microfilm - I think same index is on www.imuseum.im - many wills have been 'ironed' ready for rephotographing - the manx museum charges for scanning documents + you may want to ask library@mnh.gov.im they can take credit cards
