Wm owned several properties - if you look at my CD I try to explain the format - you should now look at the later lib asseds for one of these properties - if there is a change in the period covered by the book there will be a date m1755 for example against the name - now go to lib vas Michael for May 1755 and look to see what the change was - continue this and you get the history of this property and the sequence of owners - the rent values are often the key to identifying the property - the deeds if a sale,contract (or mortgages - these are indexed elsewhere) will give details otherwise the transfer is by will/decree.
