Originally known as the Trinity Baptist Church in Christ, this congregation was formally organized on January 23, 1876, by the Rev. D.S. Snodgrass. Charter members included J.R. and Rachel Shaw, Mrs. S.J. Knox, O.G. Shaw, Dr. and Mrs. J.M. Arnold, and Catherine Turner. During Snodgrass' pastorate, which lasted until December 1877, a Union Sunday school was organized and a sanctuary was built on land donated by the International & Great Northern Railroad. Despite early setbacks, such as a 1909 fire that destroyed the church building, the congregation grew in numbers and provided significant service and leadership to the community. The current name was adopted in 1934 upon the completion of anew sanctuary in memory of Dorcas Sheffield Wills. Over the years, several members of the congregation have been licensed to preach. The Calvary Baptist Church of Trinity was formed by a group from this fellowship. An important part of the religious heritage of Trinity, Dorcas Wills Memorial Baptist Church continues to uphold the ideals and traditions of its nineteenth-century founders. (1985)
