Riversdale Historical Society

Riversdale Historical Society Today, this architectural gem has been restored to reflect the lifestyle of the Calverts in the early 19th century.

Riversdale, an elegant Federal home, was constructed between 1801 and 1807 for Henri Stier, a Flemish aristocrat, and completed by his daughter Rosalie and her husband George Calvert, grandson of the fifth Lord Baltimore. Archaeology, archival records, and oral histories are used to provide modern-day visitors with a better understanding of 19th century life. Rosalie Calvert's letters are used to piece together the life of a gentry-class woman living in rural Maryland. Adam Francis Plummer, an enslaved man owned by the Calverts, wrote a rare first-person account of slavery. Their stories have been preserved and are retold at Riversdale. The museum is open to the public for docent-guided tours and for a variety of special events. It may also be rented for weddings, receptions, luncheons, and business meetings. The Riversdale Historical Society, a volunteer organization, works with M-NCPPC staff to preserve the cultural heritage of Riversdale and maintain the mansion as an historic house. This page is run by the Riversdale Historical Society. For more information, visit us at www.riversdale.org or http://history.pgparks.com

September is National Classical Music Month. Take a look at this sheet music book, filled with works by classical composers.

In 2014, Calvert descendant Ned Fenwick donated this leather bound book of piano sheet music to the Riversdale Historical Society. It was discovered in a drawer on the piano forte that had originally been at Riversdale (crafted by Charles Pommer of Philadelphia) which has also more recently been donated to RHS.

The book bears the mark of George. E. Blake, a noted music engraver and publisher in Philadelphia, who was active in his profession from 1803 until the 1850s. By 1810, he claimed to have the largest assortment of music in America, and was noted for publishing full scores of the American theater, opera librettos, original American compositions, political songs and minstrel music. The book notes the address of 13 South Fifth Street in Philadelphia, where Blake had a small music store.

To make the discovery of the book even more exciting, it bore the name “C. M. Calvert”, stamped in gold foil on its cover. Did this mean this book was one used by George and Rosalie’s daughter Caroline, to learn to play the piano? Pursuing our research further, we found Caroline’s signature on a title page, and we were able to verify it by matching it with other examples we have of her writing. It seems clear then, that this was indeed Caroline’s piano book. 

The book includes works by various composers including: Mozart, Fiocchi, Gelinek, Schmitt, Clementi, and Latour. Just imagine that piano music floating through Riversdale? 🎼

Happy Birthday to twins, Robert Francis and Nellie Arnold Plummer!

Nellie & Robert were the last two children of Adam and Emily Plummer. Nellie became a teacher and author. She published her family's history in 1927, "Out of the Depths. Or, The Triumph of the Cross." Robert became a pharmacist, businessman, husband, & father.

After they were born, Emily sent a letter to Adam to let him know of their arrival. At the time of their birth, Adam was enslaved at Riversdale and Emily was enslaved near Ellicott City, MD.

"The Friday night, September 7, 1860, after I wrote you I was confined with two babies, one is a boy and one is a girl. Everybody that has seen them says they are the finest children they ever saw... I am as well as can be expected. The children are well and join me in love to you."

Out of the Depths, Or, The Triumph of the Cross, by Nellie Arnold Plummer, 1927

Today is National Read A Book Day!

Rosalie Calvert often relied on her Belgian relatives to send her new reading materials. In 1808, she discussed her favorite genres with her brother Charles. She also told Charles that she was part of a group (like a book club) that borrowed books from each other and discussed them. Are you in a book club?

If you are looking for a book to enjoy, check out "Mistress of Riversdale: The Plantation Letters of Rosalie Stier Calvert, 1795-1821," edited by Margaret Law Callcott to learn about life at Riversdale in the early 19th century.
