This is the Mt. Holly (North Carolina) Band. My grandpa, Ralph Sidney Underwood (1889-1986) has the "tick mark" on the second row.
On the back of the photo in Grandpa's hand is the following:

When Grandpa wrote the above, he was the last surviving member of the band. He was born in the Riverbend section of Gaston County, NC, but grew up in Paw Creek, Mecklenburg County, NC, from 1900 on. I havent looked these guys up to see if they're on WT yet, but it would be a cool project.
