Armstrong City on the Raymond family tree
Armstrong City was a city on Luna. This colony was founded in the late 21st century. Tony Graf Raymond, a descendant of Clare Raymond, was born in this city in the late 21st century. (TNG-R: "The Neutral Zone", okudagram)
The name came from the remastered Clare Raymond family tree.
Like Lake Armstrong, Armstrong City was probably named after Neil Armstrong, who was the first Human on Earth's moon in 1969. (Star Trek Encyclopedia, 2nd ed., p. 22)
