Hello Ewan,

I don't find the Manx BMD records very easy to look at because the edges of pages are often shadowed and you can't search by first name. Do you know about Manx Lawsons? Most burials are there. Otherwise, if you're not on the island, you'll have to wait for the Parish records to go on-line, via the imuseum, probably next year. With those, you might be able to search by first name alone.

Did she revert to her maiden name? Could she have remarried? Not easy! Good luck!
