By 1900, 12 large, often intermarried families dominated the village of Tennallytown, including the Harry clan, whose five generations lived here. At the edge of what was once Harry's Field, a favorite community playground, the family's roots in Tenleytown reached back to John O. Harry, a U.S. postmaster who died in 1864. His grandson John B. Harry, known as Bernard, was born at 4509 Wisconsin Avenue in 1867, left school at age 12, and at age 20 opened a grocery store in Foggy Bottom with a partner. For the next 69 years, Brooke and Harry's served neighbors and delivered to local elite families, including J. Pierpont Morgan and occupants of the White House, while the family's home-grown strawberries were favored by President Franklin Roosevelt and Theodore Roosevelt was known to stop at the Harrys' apple orchards here. Brooke and Harry also operated an ice company, a bakery, and a car showroom on nearby Wisconsin Avenue. Family lore held that when Bernard built 4301 River Road in 1907, it was still out in the country on a dirt road. Four of his six children later built homes on his land, and their children remembered moving freely among the family households. During World War II, Bernard lent neighbors more than 50 plots on Harry's Field for victory gardens. Bernard's house and his son John's house next door were later demolished when Georgetown Day High School bought Harry's Field for a new campus.
