Dorothea McKenzie (1737-1805)
Dorothea McKenzie, the daughter of a Quaker ironmaster, became a widow at the age of 38, never remarried, and, until her death, ran a genteel boarding house in Carlisle with the help of her slaves. Dorothea’s father, Thomas Maybury, established the Green Lane Forge in the Perkiomen Valley in what is now Montgomery County, Pennsylvania as well as the Hereford Furnace. Her mother, Sophia Rutter, was a descendant of Pennsylvania ironmaster, Thomas Rutter.[1]
