The Preen Family History Study Group exists to research the history of the Preen Family. They also publish books such as this one and meet every year in a place where some part of the Preen family lived in earlier centuries. In June 2010, it was the 21st such reunion and the meeting was held in Parlors Hall, Mill Street, Bridgnorth.

A recent DNA study has shown that the Preen family is divided into three main groups. The one we call the "Bridgnorth Group" has as its common ancestors Frank Preen and his wife Fanny who lived in Mills Street, Bridgnorth during the seventeenth century and so lived through the Civil War and the siege of Bridgnorth castle. Some of their descendants lived in Bridgnorth while others moved to Birmingham or the Black Country.
