When first purchased the stone mason would work on the MI in "comfort " in his shed /workplace before transporting it to the grave. Later subsequent names would be added
at the grave. I have heard a mason tapping away while partially hidden by a little shelter of canvas on a bleak , windy day working on another line. I wouldn't be at least surprised if some
insisted on taking down at least a small stone & taking it away to work in the dry . If a very cheap stone was all that could be afforded after early deaths later family might replace it with marble
& then of course the MI could be completely re worded .It can obviously have been made more concise one hopes no important info. was lost. My Great Grandparents heavy , cheap , first stone is face
down on the grave. I would like to read it but it would cost a fortune to raise & this might cause damage. The IOMFHS record book would only have the second MI copied by someone on their
knees. What dedicated people they were.
