Marion Theresa (M. T.) Biddle was born on March 11, 1840, in Chesapeake City, Cecil County, Maryland and died on March 22, 1869 at the age of twenty-nine.
She lived with her parents, William Eugene Biddle (b.ca.1797), a farmer, and Armina Nichols Biddle (b.1825) at "Hispaniolia." "Hispaniolia" was located near Chesapeake City and Elkton, Maryland, as noted on the postmarks on four envelopes included in the collection. M. T. was the eldest of at least six children, one of whom was a younger sister Isabell. She was a teacher and signed all the letters "Prof. M. T. Biddle." Maggie R. Thompson (b.1843), the recipient of the letters in this collection, lived in Nottingham and later Oxford, Pennsylvania. She refers to a younger sister, Ellie, and twin sisters in the letters. M. T. and Maggie attended school together, possibly the Oxford Female Seminary. Thompson was unmarried when the letters were written and M. T. Biddle addressed her as "Dr."
