There was a Captain Dill in the 6th Arkansas but I'm not up enough on them to know if this is the Dill mentioned. Bryan could answer better than I could.

Those other records I posted about McRae being the mustering officer sent to Searcy are from the O.R.

The UA has a ledger from the Ark Military Board with the following description:
An official account ledger maintained by the state of Arkansas detailing purchases from various individuals and businesses. The ledger was looted from the State House in Little Rock (Pulaski County) by Private Johann Afelt, Third Minnesota Infantry, in late 1863. The first section (44 pages) of the ledger records transactions at Little Rock from October 30, 1861, to January 3, 1862.

If this one was looted there very well may be some stuff out there in private hands or in other collections
