Thanks, Laura! That's definitely him! The physical description matches the one in his CSRs. And that 20th of March date makes a lot more sense timeline-wise.@Zella if you haven't already read it, you might find some information in here. Seems like the 64th NC was dealt some unusual assignments and had pretty unorthodox history.
Histories of the several regiments and battalions ... v. 3. Clark, Walter, 1846-1924.
This is not the information youre looking for but you might like to have it. Its not in his regular carded records of the 2nd Battn or the 64th but you guessed it -- from Miscellaneous files.
