Ever since the visit of Obama to Ireland, people have had an increased interest in their own family tree and where they come from. Dr. Susan Hood is assistant librarian and archivist at the Representative Church Body Library, Churchtown, South Country Dublin. She was involved in some very interesting genealogy studies, including one with Graham Norton, for the series, Who do you Think you Are? Here she explains to Rev. Patrick Lawrence what records are kept in the Library and why they are so important.
