I was curious if anyone knew of these regiments, I have found no information on them.

LeGardeur's Company, Louisiana Light Artillery (Orleans Guard Battery)

1st Regiment, Chasseurs a pied, Louisiana Militia.

These regiments I do have info on that my family (Pellerin) served in.

8th La--Had 2 "Pellerin's" in this regiment.(Both were in company "C" both were corporals). Don Louis and Edmond Pellerin.
3rd La Cav (Harrison's)
1st Regiment, Louisiana Heavy Artillery (Regulars)
Crescent Regiment, Louisiana Infantry

Thank you for any help on the two organizations I have no information on.
