For army trombonist Spc. Joseph Murrell, the military might just be destiny. According to his family research, almost every man in his paternal blood line — except for his father — served the military in some way. The legacy started when Murrell’s long-ago ancestor, Pvt. William Murrell, joined the Union Army in 1863. A runaway slave, Pvt. Murrell had fled to Ohio and served in the 109th United States Colored Troop.
