The earliest recorded use of the "Colesville" name was on January 25, 1806, when the General Assembly of Maryland changed the place of holding elections of the Fourth Election District of Montgomery County to "Edward Berry's, commonly called Coale's-Ville". It is unknown where this name came from, but it may have come from the maiden name of Elizabeth (Coale) Snowden, wife of Richard Snowden who was the owner of "Snowden's Manor" in nearby Sandy Spring and began living there in 1728. By 1824 the name was generally known as "Coalsville", and was sometimes referred to as such even as late as 1906.
