Question: While looking through the census I note a son of my third great grandfather with an odd occupation in 1850. I am not sure what his son was doing if his job was a "marbler"? I assume it has something to do with stone cutting.
Answer: Actually a marbler was not a stone cutter or worker of marble. A Marbler was the name for one who produced the covers and end papers of books and ledgers that had marble swirled appearance. To book collectors a beautiful marble cover is just as beautiful as a marble statue. It would be interesting to see if his later occupations continued in the book manufacturing trade.
