The Category:Augustine, Florida refers to St. Augustine, a well known city on the east coast of Florida. It is listed correctly in the John Prescott Whitney family group, from Pierce. I do not understand how Wiki created the category of "Augustine" since it never appears by itself. It may be a bug in the software which doesn't group the whole name. However, as a note, apparently Pierce abbreviated St. Augustine, as imported, to "St. A". I did not want to change the Pierce quote to edit that.
