I got the information from:
www.iomfhs.im/lawsons/LawsonBMD/Main_Site_index.html

A very useful resource. I had a quick look for a marriage but couldn't see one... She may have married off Island?? Or she may have been a Spinster.

I'll have a look for the gravestone if you like. Someone out there in internetland might be able to look up the Memorial Inscription for you before I get to the gravestone (assuming I can find it).
