Graduating Class of 14

This looks like a graduating class,boys all dressed up, girls with corsages, 14 young people, date could have been 1850's-1880's.

This photo was found at the Tulsa, OK. flea market, the vendor probably purchased it at a farm/estate sale in OK. The names have faded a bit, I might have made some mistakes interpreting the writings/spellings. All have last names except 3. Wonderful photo !
People in photo include: Alf Whittaker, Anna Heacock, Carrie Holmes, Mary Pottinger, Ben Fowler, Minnie Carter, Effie Tornshell, Eva Patty, Cora Payne, Dora Ferguson, and Wilson Coons
