Growden Mansion, also known as Trevose Manor, is a local historical landmark in Bensalem Township, Pennsylvania, USA. It played an important role in early Bucks County history. The mansion sits along the Neshaminy Creek in Bensalem, a township that borders the northeast section of Philadelphia, in the northeastern United States.
The history of Growden Mansion dates back to the late 17th century, around October 24, 1681, when Cornish father Lawrence Growden and his son Joseph Growden, a rich pewterer family from St Merryn, purchased about 5,000 acres (20 km2) from William Penn. In 1683 Joseph Growdon settled on this land and built "The Manor of Bensalem" for their family. Joseph Growden had a son, Lawrence Growden, born on March 14, 1693. He then had two daughters, Elizabeth who married Thomas Nickleson of Philadelphia, and Grace Galloway who married Joseph Galloway. Grace and Joseph Galloway inherited the land on October 18, 1753, and inherited three tracts of land, Trevose, Belmont (Bensalem, Pennsylvania), and Richelieu in Bensalem township containing a total of 1,425 acres and four tracts in Durham Township containing iron mines and furnaces. The Growdens also acquired property in Bristol (as Lawrence Growden was named the Merchant of Bristol in 1730) and Philadelphia from Front St to 4th St, down to Lombard St in Philadelphia. Since women could not own property during that time, Galloway became the sole proprietor. After finding out that her husband was a Tory (British Loyalist), he was exiled to England taking their daughter Elizabeth with him. Grace Growden Galloway extensively fought to keep and maintain the rights to the properties in which she inherited. Grace kept an in-depth diary about the struggles and hardships that she faced. Once a part of the wealthiest and most notable families of the day, he reputation was ruined by her marriage to Galloway. She noted in her will that those properties should be passed on to her daughter, Elizabeth (Betsey), upon her death. Grace Growden died on February 6, 1782, and Joseph Galloway died on August 29, 1803. Their daughter then had inherited the land and sold it in 1848, when the house again underwent major changes.
Galloway was good friends with William Franklin, Benjamin Franklin's son. Franklin often visited him at his many estates, traveling 25 miles to Trevose from Philadelphia on horseback or by carriage. While a local legend maintains that Franklin performed his famous kite-flying experiment at Growden Mansion to prove that lightning was the same as static electricity, the broader consensus is that Franklin flew his kite closer to his home in Philadelphia. Other significant historical figures such as George Washington and John Adams have also stayed at the mansion.
The Growden property developed over time and was considered to be one of the strongest and most unique manors of its day. The home is now operated as a museum by the Historical Society of Bensalem Township. It includes an outbuilding called "The Vault" where the early deeds and county records used to be stored, and the main house still has bullet holes from the Revolution pockmarking its walls.
