To Apostrophe or Not to Apostrophe - That is the Question

Interesting little item in The Washington Post's Sunday "Answer Man" column about the proper spelling of Prince George's County, Md. It seems that back in the day the name of the county - a close suburb of the Washington, D.C. Metro area - was spelled without the apostrophe. A 1931 Post article reported that the original name was spelled without an apostrophe. We cannot be certain because because the original "engrossed acts" of the Maryland General Assembly were destroyed in a State House fire in 1704 which would easily resolve the matter. In 1952, the Answer Man (John Kelly) reports, a Maryland state archivist insisted that the apostrophe was correct. "It just wasn't used often in the 17th century," the archivist reportedly said. But there's more: For the most of the 20th century, The Post did not use the apostrophe as a matter of style nor did the local Post Office. However, in 1947 the Prince George's Press Association urged its member publications to use the apostrophe. In 1965 The Post began to use the apostrophe and in 1965 the Post Office followed suit. I wonder how many other counties have similar disputed name stories?
