Biography:

Deborah Washington Duvall was born on December 5, 1802, to Dr. Benjamin Duvall and Deborah Jackson Duvall. She married Thomas Canby III, a Pennsylvania-born teacher at the Fair Hill Quaker School, on January 28, 1824.1 However, she does not appear in the Maryland State Archives' records as an actual member of the large Quaker population in Montgomery County. Deborah and her husband lived in Colesville during the first twenty years of their marriage, producing seven children: Virginia (b. 1831), Laura M. and William Mauduit (1834), Benjamin D. (1838), Eliza A. (1840), Mary B. (1842), and Martha H., nicknamed Pattie (1845).2 Their oldest daughter Virginia was baptized in Prince George's Parish, also called the Rock Creek Parish, in Prince Georges County,3 but probably died before 1850. Laura married Richard T. Willson in 1853, while Mary wed Zachariah Berry in 1865.3 Thomas Canby III died sometime between 1850 and 1857. 

The Canby farm included both free and enslaved labor. In 1860, the census recorded two free blacks named James Canby and William Canby living at Rose Hill as farm laborers.7 Three years earlier, Deborah's father had bequeathed her 300 acres, his circa-1800 manor house Rose Hill,5 and four slaves: Aaron Putnam, Lewis Swams, Remus Boswell, and Jacob (last name unknown). Her three youngest daughters also inherited the slaves Lydia Boswell, Elizabeth Boswell, and Airi Thomas.6 All of these slaves should have received their freedom through Maryland's statewide emancipation in 1864. However, Jacob had already disappeared sometime after 1857, while Lewis Swams had died in prison while serving a twelve-year sentence for assisting runaway slaves.8

The 1862 prisoner record for Lewis Swams stated that Deborah Canby was living in Sandy Hook at the time, a community located near Harper's Ferry in western Maryland. Canby may have joined the many women who attended wounded Union soldiers at the Sandy Hook Field Hospital during the war, as recorded in an 1864 report by the United States Christian Commisssion.9However, more likely the clerk had simply misprinted Sandy Spring. The fact that two of her sons sided with the Confederacy during the Civil War makes her ministering to Union soldiers even less probable. Benjamin Canby enlisted with the 1st Maryland Cavalry, a Confederate battalion, while his brother William was imprisoned in 1864 for sheltering a Confederate spy, Lieutenant Walter Bowie.10

Deborah Canby died on December 6, 1864, and was buried at Grace Church Cemetery in Silver Spring, Maryland. She bequeathed all of her property to five of her six children, inexplicably excluding Benjamin, with the brief instructions to "share and share alike."11
