In 2002 I completed a history titled  “In Search of my Ancestors”  and shared it with other Breretons I met during 2001 Brereton Reunion in Cheshire (organized by Derek and Pamela Brereton).  The history was eventually posted on brereton.org  What started as an interest in Brereton Hall and the family of Lord Brereton of Leighlin has expanded so much over the years to include histories of other branches of the family, including the Breretons of Ireland, descendants of Sir William Brereton, who settled in the  6th and 7th centuries.
