CAMBRIDGE — When Marjorie Dixon Roxburgh volunteered as a garden tour guide at a historic house in East New Market several years ago, she didn’t expect to get involved with it. Not only did she end up involved but absolutely enthralled with the history of the house and its previous owners.

The end result of this involvement comes in the form of a book titled “Buckland Then ... and Now and Colonial Dorchester County, Maryland,” that is as beautiful as the home that inspired. This limited first edition book is the result of exhaustive research that reveals information about the house builder, John Rix, circa 1740. In addition, many of East New Market’s fine historic homes are showcased as are the land grants and early property owners.

Ms. Roxburgh will speak about her research for the book on April 29 at the Heritage Museums and Gardens of Dorchester at noon. She will share about the many different research topics that were revealed through her own Dorchester digging. From family genealogy to British rule of Dorchester County — many items will be discussed.

Admission is free and open to the public, although donations are always appreciated. The book will be available for purchase with personalized autograph.

The Heritage Museums and Gardens of Dorchester is located at 1003 Greenway Drive, off of Maryland Avenue East in Cambridge. For information, call 410-228-7953 or e-mail dchs@verizon.net.
