Triadelphia was a small town on the Patuxent River near Sandy Spring in Montgomery County. It was founded in 1809 by "three brothers" (that is, brothers-in-law) Caleb Bentley, Thomas Moore, and Isaac Briggs. Thomas Hyatt Lansdale was an early resident. He and his son, Thomas Franklin Lansdale, milled cotton there until the Civil War, and the Lansdales lived there until 1890 when they moved to Davidsonville in Anne Arundel County. The town was flooded in the mid-1940s to make a dam.
There are two more recent essays than these. Mary Charlotte Crook, "The Tale of Triadelphia, the Town Beneath the Lake," published in The Montgomery County Story 33.3 (August, 1990): 117-128, also contains much about the Lansdales who lived there, and is available from the Montgomery County Historical Society for $3.00. Also see the essay above by Grover Hinds.
The Sandy Spring Museum website includes history and images of the Lansdale and related families from the nineteenth century; see the section on "Triadelphia."

Alice Vedder Farquahar, Notes about the Triadelphia Bell, a brief note, with no date. The "Tom Lansdale" who signed the note at the bottom is (I believe) Thomas Franklin Lansdale, Jr., the son of the Tom Lansdale who is mentioned in the note. (Posted Sept. 19, 2004; 1 page)
