Understanding Dit names

By July 8, 2010

Follow me on:

Found primarily in France, New France (French-Canada, Louisiana, etc.), and Scotland, dit names are essentially an alias tacked on to a family name or surname. Dit in French is a form of the word dire, which means "to say," and in the case of dit names is translated loosely as "that is to say," or "called." Therefore, the first name is the family's original surname, passed down to them by an ancestor, while the "dit" name is the name the person/family is actually called or known as. Dit names are used by families, not specific individuals, and are usually passed down to future generations, either in place of the orginal surname, or in addition to it.

Why a dit name? Dit names were often adopted by families to distinguish them from another branch of the same family. Interestingly, many dit names derived from military service, where early French military rules required a nom de guerre, or nickname, for all regular soldiers. The specific dit name may have been chosen for many of the same reasons as the original surname - as a nickname based on trade or physical characteristics, to identify the ancestral place of origin (Andre Jarret de Beauregard, where Beauregard refers to the ancestral home in the French province of Dauphine), etc.

A dit name can be legally used to replace the family's original surname, so you may find an individual listed with a dit name, or under either the original surname or the dit name. Dit names may also be found reversed with the original surname, or as hyphenated surnames.

  • Hudon dit Beaulieu
  • Beaulieu dit Hudon
  • Hudon Beaulieu
  • Beaulieu Hudon
  • Hudon-Beaulieu
  • Beaulieu-Hudon
  • Hudon
  • Beaulieu

When recording a dit name in your family tree software, it is generally standard practice to record it in its most common form - e.g. Hudon dit Beaulieu. A standardized list of dit names with their common variants can be found in Rene Jette's Répertoire des Noms de Famille du Québec" des Origines à 1825 and Msgr Cyprien Tanguay's Dictionnaire genealogique des familles canadiennes (Volume 7). Another extensive source is The dit Name: French Canadian Surnames, Aliases, Adulterations, and Anglicizations by Robert J. Quentin. When the name is not found in one of the above sources, you can use a phone book (Québec City or Montréal) to select the most common form, or just record it in the form most often used by your ancestors.

Great article easy to understand. References were unknown to us, we will add to our references lists on Meaning of Names, and to Our French Canadian Roots. Dit names are difficult to keep track of and this article covers it well.

Dit naming was also used to identify cadres of soldiers. Most often they referred to the
surname of the (military)formation as a hailing recognition factor. In the confusion
of battle, it was always necessary to be able
to direct the formation to a particular action
for succesful maneuvering. As the dit naming
would recognize “Andre Jaret Dit Beauregard” it further identified Andre Jaret as a soldier
of the unit that was directed by the “Beauregard” commander or possibly by the captain whose surname was BEAUREGARD . These
were some of the basic tenets of battlefield
tactics that were among the first rules that
an officer had to learn.

Maybe you can assist me with my ancestral “dit” mystery. My 4th generation great grandfather name was Mathieu Devaux dit Platillo. Born in Marseilles, france came to spanish colonial louisiana sometime around 1763-1770. First discovered on a militia list in the city of New Orleans Louisiana 1770.

I am a bit confused by the use of the dit Platillo. It was used twice in two documents while he was still actively involved in militia service however all other documents found after 1783 has only his name Mathieu Devaux.

You mention dit could refer to a particular trade. Someone once told me Platillo had to do with the silver trade. any suggestion on figuring out this mystery.

I’ve started keeping a cross-reference of some of the French Canadian names. It’s a simple Excel spreadsheet format, and lists known names and variations of many names. I keep adding to it as I enter names in the software. As a result of the chart, I’ve discovered up to 8 variations, not just switching places with 2 names, but 8 different variations and up to 20 variations if I include the patterns used in the article. And since it’s in Excel, I can easily alphbetize and sort the names too. Thanks for the article.

I have to show some thanks to the writer for rescuing me from this particular difficulty. Because of exploring throughout the world wide web and coming across tips that were not powerful, I believed my entire life was well over. Existing without the presence of strategies to the difficulties you have sorted out all through the article is a serious case, as well as those that could have in a negative way affected my career if I had not discovered your blog post. Your personal talents and kindness in touching almost everything was priceless. I’m not sure what I would’ve done if I had not come across such a step like this. I can at this moment look ahead to my future. Thanks a lot very much for the specialized and sensible guide. I will not hesitate to endorse your web sites to anyone who wants and needs guidelines about this subject.
