see my Peel property pages
http://www.ee.surrey.ac.uk/Contrib/manx/towns/peel/property.htm and in particular those rolls post 1740 when 1 book lasted for a decade or longer
entries annotated m17xx = deed (ie a change in tenant) passed through court in May of that year o17xx in October of that year
underlining = change to be noted in next roll - the /'s are the continuation of the underling to bring out to a month/date so that the compiler could find the entry in the Lib Vast (ie the Lib Assed gave a static view - the lib vast noted the changes
