As for the name, if I had to guess, I’d say it was from the living there being hardscrabble in the old days. The town was mainly African-American in the past and had a Rosenwald School that now houses a senior center and museum. These schools were built by a foundation dedicated to improving the education for African-American communities, mainly in the south. Scrabble School was opened in 1921 and used until the school system was integrated in 1968. See https://scrabbleschool.org/ for more information.
