New Trinity Cemetery. When the Rev. Greene Fretwell, a former slave, died in 1886, there was no black cemetery in this part of Tarrant County. With donations collected by his widow, Frances, the trustees of Trinity Chapel Methodist Church bought two acres in 1889 for a church and burial ground. Worship services were held under a brush arbor until a frame church was built here. By the 1920s, burials began on adjacent land, known as New Trinity Cemetery. Additional property was designated in 1931 as People's Burial Park. Today the three sites are commonly called New Trinity Cemetery. #14414
