[2] Magruder owned approximately 4,000-acre (1,600 ha) of land in Maryland, and some of his properties, such as Good Luck, were named after locations in the Scottish Highlands.

Located on the Baltimore and Potomac Railroad, Glenn Dale prospered, and in 1876, Good Luck's post office was moved there.

[6] "Good Luck Road" is still located at the site of the former settlement, which is currently occupied by the Goddard Space Flight Center and a residential community.

[8] A census-designated place (CDP) called "Good Luck" was established in the general area of the former settlement during the 1970 United States Census.

[10] In 1980, Good Luck CDP ceased to exist after the census area was split to create the CDPs of Glenn Dale and Goddard.
