Just to put some completion on this, Frances convinced me that what looked like a double f (ff) at the front actually isn't. I now think the name of Philip Cotteen's wife is Margaret HANTON. The "t" in the middle that I doubted for awhile is a "t". There were HANTON's around Lonan in the early 1700s and earlier than that in Braddan and others. Lonan register information does not exist prior to 1718, which makes it difficult. Many thanks to Frances and Brian for their ideas and to Frances for studying the scan of the will.
