The Connect 1900 page (aka La Belle Époque) has been dormant for a while. I've just added a section dedicated to ongoing work on the Champsaur Connection :
Le Champsaur is a small valley in France, Hautes-Alpes. See https://fr.wikipedia.org/wiki/Champsaur
In the late 1800s, thousands of people (estimation about 5,000) left their villages in Champsaur to seek fortune in various parts of America, most of them in the USA, California, Washington, some in Argentina. This emigration was massive, about one third of the whole population left. Given the previous strong endogamy, most of those emigrants were parents or closely connected.
There are several branches of Champsaur descendants in WikiTree, but they were mostly created independently, and not directly connected to each other. They are in various quality shapes. Some profiles need to be sourced and expanded, etc. Work is in progress to connect all those branches together through their Champsaur families, with the help of excellent local access to data and sources ...
See the linked page for more details and examples. Feel free to answer here if you are related to any of those emigrants, and if you can help.
Check how far you are from (maybe the most notable of those migrants) Germain Pellissier. His descendants gave the name to a still famous Los Angeles building.
