According to a State of Indiana History textbook which my grandfather owned, and now my dad has, Deputy, Indiana was founded by someone by the last name of Deputy years ago -- I don't know when. He canoed down the Ohio River with an Indian Guide and settled in southeastern Indiana, where Deputy, Indiana still exists. My grandmother on the Deputy side had someone do some research, which indicated that the name came from the original DePuy. This same research indicated that the original DePuys were French Huginots (sp? Some of the first Protestants), who fled French religious persecution. Some went to Holland, but those from whom the Deputys are descended fled to Wales. A former coworker of mine, who hailed from Wales, recognized my name as Welsh immediately upon being introduced. Thats about the limit of what I know. My grandfather insisted we were related to four American Presidents: the Adamses and the Harrisons; however, a cousin who has researched our genealogy says she hasn't found any connection.
By the way, be careful what you say on this or any other geneology/ancestry website. According to news articles I saw a few months ago, identity theives are using info from these websites.
