Joined and re-joined muster rolls
United States—Enlisted and Officer Muster Rolls and Rosters, 1916–1939 [Part N][M3JZ-XC2]
I accidentally submitted the last page on had this question on so I will try it again.
On this muster roll it has "joined" and "re-joined" with dates by the side of some of the servicemen. Is this the same as an "enlistment" or "re-enlistment" date?
Do I use the "joined" date or the muster roll date for these servicemen?
