ジャーマンタウンの町として当初の計画は、1つの中心街と6つの町内ビレッジに分けるというものだった[3]。すなわち、ガナーズレイクビレッジ、キングスビュービレッジ[4]、チャーチルビレッジ、ミドルブルックビレッジ[5]、クロッパーズミルビレッジ、ニールスビルビレッジだった。メリーランド州道118号線とミドルブルック道路の角にあるチャーチルタウンの部分は、ジャーマンタウンの中心街あるいは中心部に最もよく似ており、これはアップカウンティ地域サービスセンター、ジャーマンタウン公共図書館、ブラックロック芸術センター、リーガル・ジャーマンタウン・スタジアム14があり、またレストランが並ぶショッピング街があるからである。州間高速道路270号線の3か所ある出口は1マイル (1.6 km) と離れていない。メリーランド地域通勤鉄道の駅は歩いて行ける範囲にある。ジャーマンタウン交通センターからはライド・オンのシャトル便が出ており、ワシントンメトロのレッドラインにあるシャディグローブ駅に行くことができる。

Before that time school was held in people's homes. In 1868 there was a one-room school on built on Rt. 118 near Blackrock Road that served the children of both Germantown and Darnestown. In 1883 a larger one-room school was built closer to Clopper Road to teach the children of Germantown. Another new school was built in 1910 on the present site of Germantown Elementary school. This school had four rooms--two downstairs and two upstairs--each room housing two grades. After eighth grade the children rode the train to attend high-school in Rockville.”

Many of the families of German descent were against slavery and had sons fighting in the Union army. Many of the families of English descent owned slaves and even many who didn't had sons fighting in the Confederate army. Many people who had formerly been friendly went out of their way to not have to deal with each other, some changing churches, or going to a mill or store miles distant from the one they usually used.”

Sometimes these soldiers would come to the stores in Germantown. In September, 1862, and June, 1863, many regiments of Union soldiers marched north on Rt. 355 on their way to the Battles of Antietam and Gettysburg. In July, 1864, Gen. Jubal Early led his Confederate army down Rt. 355 to attack Washington, D.C. Confederate raiders also came through the area several times during the War. Local farmers lost horses and other livestock to the armies of both sides.”

When he was about 16 his father moved the family to Virginia, but George still had many friends and relatives in Germantown. He was living in Port Tobacco during the Civil War, and supplementing his meager income as a carriage painter by smuggling people across the Potomac River in a row boat. This clandestine occupation brought him into contact with John Seuratt and John Wilkes Booth and he was drawn into a plot to kidnap President Lincoln. On April 14, 1865 John Wilkes Booth gave George Adzerodt a gun and told him that he was to kill the vice president, Andrew Johnson. George panicked when he found out that Booth had shot President Lincoln and made his way to his cousin's, Hartman Richter's, house in Germantown to hide. He was discovered there by soldiers three days after the assassination and, although he had never actually committed a crime, was hanged with other conspirators on July 7.”

Electricity was brought into the mill and also served the homes and businesses nearby, making this the first area in the northern part of the county to get electricity.”

For a while the old and the new mixed as employees of the Atomic Energy Commission (now the Department of Energy) came to the old Germantown store for lunch and Mr. Burdette's cows often had to be cleared from the road. When the sewer line was completed in 1974 building in Germantown began in earnest.”
