HistoryA character grade: shown, never part of Galliano’s overall grade.
Louisiana towns list more on the Register than most of the country (a typical Louisiana town has 3.8 per 10,000 residents, the U.S. 2.4), so Galliano’s 0.0 sits below most of its state (21% of Louisiana towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.
How sure. Graded on two of the three inputs, so a change in either one moves the letter more than it would with three. The pre-1940 share (±2.7 points) is firm at this size.

What stands out about Galliano’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
The area was named by the late postmaster Alzec Autin, who chose the name "Galliano" in honor of an original settler in the area formerly known as Côte Cheramie. Signor Antoine Galliano settled in the vicinity in the late 1700s and had a large farm and a citrus tree orchard. He came from the Kingdom of the Two Sicilies in the vicinity of Naples, Italy, where he was in the service of the King of Spain.
