Greg,
I also have the NA Military Service Records Catalog, ca 1997.
However, the error is much larger as this is what I hastily find:
Roll 707 25th Militia
26th Infantry A-Bi
Fold.3 starts with Belvin, Edward
Hence, they miss the entire 25th Militia, 223 men per the American Civil War Research Database, and the 26th Inf.
Abbott, Elisha - Belvin, Benjamin, some 43 men.
I'll need to spend some more time to accurately document before contacting Fold.3 who by the way, haven't always answered my finds.
Thanks,
George
