Rebecca Webb Pennock received a fairly traditional education for women of the early 19th century, and married Dr. Charles Lukens in 1813.

In the records she left behind is evidence of her full knowledge of the operations and finances of the business, and her involvement in its management process, even when men were sometimes the principal actors.

Terracina is a fine example of a Carpenter Gothic country house in the style promoted by Andrew Jackson Downing; it was built by Rebecca Lukens as a gift for her son on the occasion of his marriage.

Graystone was built in 1899 by Abram Huston, Lukens' grandson; it is a high-quality example of Tudor Revival design, and until recently housed the offices of the borough of Coatesville.

Finally, the Lukens Main Office Building, located across the street from the three houses, is a prominent local example of Georgian Colonial Revival architecture; both it and Graystone were designed by the architectural firm of Cope & Stewardson.
