I recently looked up Ventura in the superb book California Place Names, by Erwin G. Gudde (pronounced “goody”), and discovered that it was shortened from San Buenaventura in 1891 by the Post Office, which was tired of dealing with the confusion caused by its resemblance to San Bernardino. The entry includes this plangent obituary for the name, by Z.S. Eldredge:
And now comes the Post Office Dept., which is the most potent destroyer of all. I have spoken before of the injury done the people of San Buenaventura. They cling to that name and use it among themselves. But they are doomed. Mapmakers, from the Director of the Geological Survey to the publisher of a pocket guide following the lead of the post office, call the place Ventura, and the historic name will be lost. (San Francisco Chronicle, Apr. 10, 1905)
This is how I feel about enforced name changes, as regular readers know, and I am glad to see it so well expressed.
