Geography in France during the Revolutionary period (at its briefest, 1792 to 1800; at its most extreme, 1789 to 1815), like the calendar, went through some radical changes and this can make researching your ancestors during that epoch very difficult. While it may be relatively easy to convert dates from Republican to Gregorian (we still prefer this converter), it is a bit more work to sort out the geographical changes.
All towns with religious names were changed. In some cases, such as Saint-Port to Seine-Port, the change made little difference, at least in pronunciation. When the country's administrative boundaries were altered, some communities were combined and some separated. Of these changes, some were retained but many reverted to their old names.
If you do not know of the change, you will find it very hard to research the civil or parish registers. Thus, if you run into such a stumbling block in your research, e.g. a town that seems not to exist, it may be time to check the Revolutionary names. There are a few online lists.
- Wikipedia's is arranged, as they all are, by department, all on the same page. Those towns highlighted in blue have retained their Revolutionary name. A third column gives a link to the commune's location on the Cassini maps.
- Geneawiki's presents a list of the departments as links on which you must click to get to a page of just that department's towns. This makes it much harder to search them all at once, which you can do on the Wikipedia page.
- The Internet Archive has the 1901 book, Les noms révolutionnaires des communes de France, which lists the towns by both department and in a general index.
These lists do not agree with one another entirely. It was an unsettled time. You may have to search them all to find that, though your ancestors may not have moved a centimetre, they lived in two or three towns because of the name and/or administrative changes.
