This photograph of Della Hines Barnes‘ Sunday School class at Calvary Presbyterian appears to have been taken at the same as this one. Della Barnes’ grandchildren Walter Dortch Hines and Elizabeth Scott Hines stand on either end of the front row. Samuel H. and Annie Washington Vick‘s son Robert E. Vick stands between them in knickers. The three were born in 1908 and 1909, which dates the photo a little later than the 1915 earlier estimate.
