This brief bio of Rev. Edward C. Simms is found in souvenir volume issued for an A.M.E. Zion General Conference. I do not have the access to the full volume, its title, or its date of publication.
REV. EDWARD CUTHBERT SIMMS, P.E., Tampa, Fla.
Rev. Simms hails from Wilson, North Carolina, and of the year 1862; he graduated from the Wilson Academy in 1883; was converted there in 1875; joining the Farmer A.M.E. Zion Church at the same time. He became a preacher in 1896 at Norfolk, Va., and joined the Virginia Conference. Later on, he was ordained deacon at Hickory, N.C., in 1897, and ordained elder at Franklin, Va., in 1899.
His pastoral labors were exerted at Mosley Street A.M. E. Zion Church, Norfolk, Newport News, Va., and Mount Sinai Church, Tampa, Fla. He built the Centreville Chapel in Norfolk County, and Zion Chapel at Bear Quarter, Va. Rev Simms is a prominent member of the South Florida Conference, and a preacher who draws and holds an audience. As a pastor his success reaches the best average. This will be his first official appearance in the General Conference. He makes a highly acceptable administrator and his constituency love, honor and revere him.
