Examples of the Buggy name from the early 19th century in America are few and far between. One recent example I came across is from genealogical transcriptions from New York City court records. In the February 1803 sessions of the Court of General Sessions of the Peace there are a number of references to a Dennis Buggy, who was the victim of theft. They read:
The following are indicted: …….Nicholas Treasey for grand larceny of the goods of Dennis Buggy;….All of the above plead not guilty. 8 June 1803
Trial of Nicholas Treasey for grand larceny of the goods of Dennis Buggy. People’s witness: Dennis Buggy. Verdict: Guilty of stealing property of the value of $12. 8 June 1803
The following are sentenced to serve the following terms in the State Prison at hard labor: ….Nicholas Treasey for petit larceny of the goods of Dennis Buggy (3 years) 13 June 1803
