The Shipley House was located in Alpha, Howard County, Maryland, near Marriottsville. The house was among five other buildings supporting a farm in Alpha, Maryland. The 55-acre (22 ha) property was part of a 3,440-acre (1,390 ha) land grant named Woodford patented in 1727. John Taylor acquired the land and 2,707 acres (1,095 ha) of the estate were sold to Phillip Hammond in 1744. In 1777, Charles Hammond bequeathed 1,500 acres (610 ha) of Woodford and his slaves to his son. Nathan Shipley acquired a portion and through inheritance, Joshua H. Shipley acquired 77 acres (31 ha) of the Woodford estate, raising 12 children on-site. The slave plantation harvested tobacco and grain crops. The frame farm house was constructed in 1830. Outbuildings included a wellhouse (1900), a frame shed (1835), and a bank barn (1884). John and Mary O'Mara farmed and maintained the property as Sunnyside Farm, raising hoses and cattle until sale in 1979. The farm was purchased by Howard County in 1979 as possible expansion space for the controversial Alpha Ridge Landfill project. The county boarded up the properties without maintenance. In August 1992, the firm of Goodwin and Associates determined that the deterioration that occurred in twelve years of ownership by Howard County negated any effort to preserve the property. The land was converted to the Alpha Ridge Community Park in 1994, demolishing the Shipley House and outbuildings to replace them with a complex of revenue generating ball fields and facilities.

Waverly Mansion is a historic home located at Marriottsville in Howard County, Maryland, USA. It was built circa 1756, and is a 2+1⁄2-story Federal style stone house, covered with stucco, with a hyphen and addition that date to circa 1811. Also on the property are a small 1+1⁄2-story stone overseer's cottage and a 2-story frame-and-stone barn, and the ruins of a log slave quarter.Waverly was a property developed on land first patented by Charles Carroll of Carrollton and later part of the 1703 survey "Ranter's Ridge" owned by Captain Thomas Browne. The land was resurveyed in 1726 as "The Mistake." It was purchased by John Dorsey and deeded to his son and daughter-in-law, Nathan and Sophia Dorsey as the next owners.The property is associated with the Dorsey and Howard families. From the time it was established through the end of the Civil War, Waverly functioned as a plantation where unpaid slave labor was used for farm operations and creation of the wealth and lifestyle afforded to the Dorsey and Howard families. Through deeds, census records and an inventory taken upon the death of George Howard in 1846, information about the enslaved population at Waverly was uncovered. A 1965 article in the Ellicott City Times claimed that 999 slaves worked on the plantation at one time, but research has shown that between 7 and 25 enslaved men, women and children is more accurate. The Ellicott City Times article does not have any primary sources to back up this claim, nor is there an author's name credited to the article.
