Saint Lucia[^1] vs St. Lucie[^2]:

> The name "St. Lucie" is originally derived from the name of a settlement near Jupiter Inlet, which was founded on St. Lucia's Day in 1566. Due to numerous errors, the name later came to be associated with the present-day town of St. Lucie Village, Florida, north of present-day Port St. Lucie. After La Florida and St. Augustine, it is the oldest still-in-use European place name in the United States.
