was a member of an aristocratic French Creole family, who first immigrated from Grenoble, France to La Louisiane (today's Louisiana, USA), in 1741.

At various points in the race his opponents include the flamboyant Bernard de Marigny, Martin Duralde, son-in-law of Henry Clay and relation of Governor William C.C.

When his term was ending, Governor Roman sought re-election, but he was defeated by Edward Douglass White Sr., another Whig.

His opponent this time was Denis Prieur, the Jacksonian Mayor of New Orleans who lived openly with his quadroon mistress.

During this administration the first practical impetus on a public education system was established: 600 volumes of Charles Gayarré's Historical Essay on Louisiana were purchased and distributed among the Parish schools.

Roman created the Office of State Engineer and advocated opening the passes at the mouth of the Mississippi River for better shipping.

The Clinton and Port Hudson Railroad, which aided the cotton industry, was established, as well as an experimental farm in St. James Parish.

In 1845, he was elected Delegate to the state constitutional convention and in 1848, Roman went to Europe as an agent for Citizens Bank and Consolidated Association of Planters for an extensions of bonds.
