On September 25, Paris dispatched Jean Pierre Isidore Alphonse Dubois de Saligny [fr], a secretary to the French Legation in Washington, to be the new chargé d'affaires to the Republic of Texas, representing the King of France, Louis Philippe.

Dubois gave multi-course dinner parties in the cabin he rented downtown as his mansion was built, and worked with legislators to bring French settlers to Texas.

The mansion was later occupied by John Mary Odin, first Bishop of the Roman Catholic Diocese of Galveston, and then Moseley Baker, a veteran of the Texas Revolution, in 1847.

At that time, the state placed the property in the custody of the Daughters of the Republic of Texas (DRT), who established the French Legation Museum in 1949.

The DRT restored the legation building and grounds in a manner similar to other house museums in the mid-twentieth century.
