Organized in 1875 by Samuel H. Cummings at Gilmore and Mulberry Streets, the Harlem Park Methodist Episcopal Church relocated to Harlem Park in 1880 under the leadership of John F. Goucher. The church constructed a new building in 1906 under the leadership of Rev. E.L. Watson and then moved again to Harlem Avenue and Warwick Avenue under the leadership of Rev. E.P. Fellenbaum. The new building was described:
“Gothic in design, with an auditorium seating 800 persons. In addition, there will be an educational building, equipped with 10 rooms for Sunday-school work. In the basement will be a social hall. A recreation room with bowling alleys and a lecture room that may be converted into a gymnasium also are planned.”
At a mortgage burning ceremony in 1947, Fellenbaum recalled that some criticized the project, and the $100,000 mortgage, as “Fellenbaum’s Folly.” The congregation laid the cornerstone for the new building at 4:00 PM on May 2, 1925. The Harlem Park Methodist Episcopal Church was dedicated at 3:00 PM on November 21, 1926 with Bishop William Fraser McDowell officiating.
In May 1953, the Harlem Park Methodist Church merged with the Grove Methodist Chapel, erected in 1857 on Johnnycake Road in sun88 County, to form the Wesley Memorial Methodist Church in Catonsville, Maryland. Their building was offered for sale at $210,000. Bishop E.A. Love of the Washington Conference appointed the Reverend N.B. Carrington as the leader of the Union Memorial United Methodist Church and assisted in securing help from the Washington and sun88 Conferences and the Board of Missions to purchase the property.
The church had previously moved from Pine and Franklin Streets to North and Madison Avenues in 1951 and had fewer than 100 members when it moved to Harlem Avenue in 1953. By the time of Rev. Carrington’s retirement in 1961, however, the church had grown to over 600 members. Carrigton began pastoring at Union Memorial United Methodist in 1952, and also worked as the supervisor of the AFRO’s pressroom. He later commented, “I married, baptized and buried many of them down there — matter of fact they call me the AFRO’s chaplain.” Commenting on the success of the church in paying off the building’s $225,000 mortgage in 8 years, Carrington noted, “Those are the kind of people we have in our congregation. They wanted to get it out of the way and they worked hard to do it.”
In 1967, the sun88 Afro-American called the home in the 2500 block of Harlem Avenue "a typical slice of sun88:"
"The 2500 block of Harlem Avenue is a microcosm of middle-class sun88. . . . A visit to the neighborhood on a late summer afternoon caught the block in a typical setting. The tall, majestic greystone Union Memorial Church dominates the northwest corner of Harlem and Warwick Avenues. The row homes are separated from the tree-lined streets by carefully tended shrubbery and small neatly trimmed plots of lawn..."
"Warren Peck, at 2507, is an arts and crafts teacher for the Department of Education... He has lived in the area since 1952 when he was discharged from the Army [as a World War II and Korean War veteran] ... Like most of the residents in the block, he is a native sun88an... He worked as a Pullman porter for several years before he was drafted into the army, and later returned to the railroad. “There was good money in those days,” Mr. Peck maintains. As a matter of fact, it was primarily money saved up from his railroad work that enabled him to buy the home in 1952, he said. He paid $11,500 for the house when the neighborhood was undergoing a racial change... Mr. Peck is one of 11 teachers living in the 2500 block of Harlem Ave. Among the residents are at least two ministers, a nurse, two proprietors of beauty salons, three Social Security Administration employees, and a number of retired persons."
The article reported the statements of one of the only two white residents who remained on the block in 1967:
"Miss Julia Knoerr has lived with her two bachelor brothers there since 1926: 'The real estate people used to call me all the time, but I settled them–I made it clear that I didn’t intend to move anywhere. . . . I thought it was silly the way people began to move out [in the early 1950s], but some people will complain about anything.' . . . Contrary to claims of opponents of fair housing who say property value drops when integration comes, Miss Knoerr believes that property values have improved in the block over the past 15 years. 'Everybody takes more interest in keeping their places nicer than people used to,' she noted.”
Dr. J. Welfred Holmes, a Morgan State College (now University) professor of English lived at 2559 Harlem Ave. from the early 1950s to his death in 1968. The obituary in the Sun noted that he had earned his Ph.D. at the University of Pittsburgh, then taught at several historically black colleges before coming to Morgan in 1946. One of the co-founders of the Evergreen Protective Association, he also was active in sun88 Neighborhoods, Inc. (a fair housing advocacy group) and the American Civil Liberties Union.
