I posted in pointing out, in Louisiana, the memory and history of militia goes futher back and deeper than its statehood. By 1861 Louisiana, as a state, was only 49 years old. The first regulations on white and free black militias goes back to 1769, writen by Spanish General Alexandro O'Reilly. Eventually the free black militias would be segregated by parda and moreno, or light-skinned and dark-skinned soldiers and officers. These units served both the Spanish and French in control of Louisiana right up til statehood; in 1811 they were used to put down a slave revolt in New Orleans and when Jackson needed them in 1815 they served. Eventually fading away under new laws, the use of the free black militias would finally be signed out of law by 1834. In 1861 their memory and members would still be available for the State of Louisiana. The use of the term Creole evokes a thought of mixed race and must be taken into account and families histories of such are common in Louisiana.
The men may not be related but Don Pedro Josef Favrot is mentioned as a member of the free pardo militia in 1788 and a slave owner. According to which family tree you look at, this Favrot is related to those I mentioned living in Baton Rouge in 1861. H. B. Favrot is supposed to be the third son of Don Pedro Favrot. H. B. Favrot lost a son in the Civil War, Corp. St. Clair Joseph Favrot, Co. F, 4th La.
