Rhoda Boyd was born in rural Cumberland County, Pennsylvania in 1748 to John Boyd, immigrant from Ulster and Nancy Urie, immigrant from Scotland. Rhoda and her siblings were captured by Lenape on 10 February 1756. The Lenape killed her mother and youngest brother during the attack.
Taken captive at age eight, Rhoda lived with the Delaware for eight years, from the age of eight to sixteen, by which time she was assimilated to the band. Liberated by Colonel Henry Bouquet at the forks of the Muskingum River, she and Elizabeth Studebaker, another English colonist adopted by the Delaware, escaped from his custody on their way to Fort Pitt in Pittsburgh, and returned to the Delaware.
Rhoda Boyd was ransomed in Detroit in 1764 and taken back to the British colonists. Bouquet took her to Carlisle, Pennsylvania in 1764. There she married American Revolutionary War soldier Thomas Robert Smiley. They had children together, and the family later moved to Somerset, Pennsylvania. They eventually moved to Tuscarawas County, Ohio, where there was a settlement of Christianized Delaware. Rhoda Boyd Smiley died there in 1823.
