The historic house, managed by the historical society and owned by Washington State Parks, provides the Rothschild family story, as well as exhibits a window to Port Townsend’s early years.

Enterprising retailer D.C.H. Rothschild was born in Bavaria in 1824 and settled in Port Townsend in 1858. His business was called Kentucky Store and was later changed to Rothschild and Co. Mercantile, selling varied merchandise, according to the historical society website.

Rothschild had his family home built in 1868. His widow, Dorette, remained in the house until her death in 1918, allowing only minimal changes, such as the installation of a bathroom.

Her daughter lived there for nearly 78 years, until her death in 1954.

The house was occupied only by the Rothschild family. The last surviving member, Eugene, donated the house to the Washington State Parks and Recreation Commission.

It opened to the public as a historic site in 1962, and is listed on the National Register of Historic Places.
