John Prettyman was one of the original Trustees of Daisy United Methodist Church in Woodbine, Maryland where he is buried in the church's cemetery. Below is text taken from the Maryland Historical Trust's Inventory accessed via the link above:

"Significance: The history of the Daisy United Methodist Church began in 1876 when the trustees of the Methodist Protestant Church acquired 0.91 hectares (2.25 acres) of land for $29.81 from Dennis P. and Leanna Gaither. The trustees of the church included Samuel Harriday, John Prettyman, Hanson Dorsey, Franklin Tyler and James Parker. The deed stated that the land was conveyed ''for the purpose of erecting thereon a Public School house to be used as a school house for colored children and also a house of public worship for the use of the colored members of the M.E. church of the neighborhood …. " By 1890, a log building had been erected on the site. A school operated in the building, and prayer services were led by a -Reverend Hawkins. The current building was constructed in 1906 to house a congregation that had grown to 125 members. The new building had a school room on the lower level and a sanctuary on the upper level. The school, known as "Daisy School Number Five," was supported in part by public funds and was dissolved during school consolidations of the 1940s and 1950s. The congregation continues to meet in the church. In 1995, the Warfield family donated an additional 0.37 hectares (0.92 acres) of cemetery space to the church (Howard County Historical Society (HCHS) Vertical Files). The Daisy United Methodist Church is located in the Daisy community. Daisy, located at the crossroads of Daisy Road and Union Chapel Road, was founded in 1892 and named for the daughter of Senator Arthur Pue Gorman. By 1904, Daisy had a population of twenty-eight. As a farming community, Daisy thrived during the mid-twentieth century, when it included a general store, a Good Templars Hall, a schoolhouse for white children (later converted to a truck repair garage) and the Daisy Methodist Church and School. The estate Oakdale, home of Governor Edwin Warfield, is located nearby. The Daisy community declined during the 1970s as profits from agriculture fell and families moved to larger towns (HCHS Vertical Files). "
