Look for the name of an owner in the name index volume that covers the year when the property was bought or sold. If you do not know the exact year you will have to work your way through the indexes, each book covers several years so this should not take too long. Between 1704-1794 names are arranged in alphabetical order by their initial letter, but not in strict alphabetical order within this. Every entry under a specific letter has to be checked, to ensure that all relevant references have been found. The next index is a place name index, which is much less useful than the personal name one.
Reference is by parish or township.
Between 1704-1787, as with the personal name index, the order is not strictly alphabetical. The last main index is a wills index which runs from 1704-1879. The usefulness of registered wills varies considerably. Having found the reference in the index, your next step is to find the volume. Volumes A-1922 are on the ground floor.
