He owned a large number of properties in the area of today's Central Business District, in the vicinity of Girod Street.

He welcomed in General Andrew Jackson who declared martial law upon entering New Orleans in December 1814, having marched overland from present-day southern Alabama and then crossing Lake Pontchartrain.

Among other provisions in his 1837 holographic will, he left a bon (obligation) of $100,000 to be applied to the construction of a facility in Orleans Parish for the housing and care of Louisiana's French orphans.
