Virgil Roberts may be your best contact. If he is home, he should have more on Quinn's 2nd Miss. Militia. Our mutual ancestor, Micajah Wilkinson of the 2nd Miss. (Quinn's) has an extensive letter collection at LSU. He and I have transcribed most of the letters that involved Micajah's brothers in the 7th Miss. There are , however, many references to locations and movements of the 2nd. I just don't have all the letters so I recommend that you wait for Virgil to respond. If you don't hear soon, email and I will try to help.
