Apparently, the two groups were unrelated. Here's what I have on them. -- Jim H.
[Note: There is evidence that a New Orleans German home guard militia unit with a similar name was formed about the same time as the Violett Guards. That unit was the Violet Rifles, formed in April 1861, with Rudolph Woeste (Wöste) as their captain. Their relationship to the Violett Guards, if any, has not been determined, due to a lack of documentation. Both Rudolphe Woeste and his apparent kinsman, J.M. Woeste, eventually ended up being captains of Fenner's LA Battery.]
[Note: There is also a "Violet Guards" militia unit from Violet Township, Fairfield County, Ohio, ca. 1844-1846. Obviously, this unit has nothing to do with the New Orleans "Violett Guards."]
[Note: There was also a New Orleans militia company called the "Quitman Rangers," which formed about June 5, 1861, just as the "Violett Guards" and the 6th LA Infantry were preparing to depart from Camp Moore, Tangipahoa, LA, for Richmond, VA, and the war. These "Quitman Rangers" should not be confused with the "Quitman Guards" who became the "Violett Guards."]
