Lancaster’s landmark Stevens House Hotel was built in the 1870s by the Lancaster Hotel Company. The Martin brothers were on the board of directors. The board named the hotel for U. S. Congressman Thaddeus Stevens. 
Barton Martin’s grandson, Ralph V. Alexander, was a manager and director of the Stevens House for many years. He was a treasurer and secretary of the hotel board. He became hotel manager in 1918. Ralph Alexander’s wife and daughter succeeded him as the hotel’s managers. (Wife and daughter were both named Mabel Alexander.) In the 1960s the hotel was demolished to be replaced by the Stevens House residential building.

  Amos S. Urban, father of architect C. Emlen Urban, owned a planing mill in Lancaster with Henry Burger for producing construction woodwork. During this same decade, the 1870s, Amos Urban was also building houses on Mary Street, on lots sold by Barton Martin. (233 - 243 North Mary St.)
Emlen Urban was a young student during this time. His father’s high-profile construction projects in the city undoubtedly had a positive impact on the architect’s future career here. Barton Martin’s brother, Jonas Martin, eventually hired Emlen Urban to build his Martin family’s home on Chestnut Hill, which became the Wolf Museum of Music and Art.
