Mounted Artillery in Missouri

[LittleJohn]

I am looking for information regarding mounted artillery units in Missouri. I am currently associated with a unit in the western part of the state, but I live in the eastern part of the state and am hoping that I might find an outfit to fall in with at a few events this spring and summer.

Is there such a thing as the St. Louis Light Artillery or 13th Missouri Light Artillery? I am outfitted to portray rebel and/or federal and my horse is sound around cannon fire.

I am specifically looking for Mounted Artillery in the eastern part of the state. Marsha Gibson of Altenburg, Missoui. Does anyone know her or what unit she represents?

Still looking for contact information for this unit. St. Louis Light Artillery or perhaps 13th Missouri Light Artillery. Any pointers to definitive points of contact would be greatly appreciated.
