Ancestry updates Northern Ireland, Will Calendar Index, 1858-1965

Additional records have been added to this Ancestry "Web" database - indicates information scrapped from a third-party source website and made searchable through Ancestry. In this case the source is the Public Record Office of Northern Ireland.
I found you're better off doing the search directly at the PRONI site http://apps.proni.gov.uk/DCAL_PRONI_WillsCalendar_IE/WillsSearch.aspx which returned more hits for a name searched from Full Abstract than found by Ancestry. The complete will is free online, where available, not just the calendar entry.
