The Evangeline's Cousins web site is a bit unusual. It is rather "barebones." That is, it is rather stark without bells or whistles. However, it does contain genealogy information. Indeed, it contains a LOT of information about Acadians: French-speaking residents of what is now eastern Canada with many of the later generations going to Louisiana where they became known as Cajuns.
The web site's home page states that it contains entries for 564,125 individuals, almost all of them of Acadian descent. The entries go back into the 1600s. Since I also have a lot of Acadian ancestors, I quickly recognized many of the surnames as being the same as those of many of my ancestors. Within minutes, I had found a number of my ancestors in Acadia in the web site's listings. If you have Acadian ancestry, you probably can do the same.
You can find any individual quickly by searching for his or her name. However, make sure you try several alternate spellings. My Theriault ancestors were listed as Teriot (which was the more common spelling in the early days of Acadia) and my Arsenault ancestors were listed as Arceneaux. As with English names, the spelling of French names varied a lot over the years. Also be aware that first names were repeated often within families. If you find an entry for Joseph Theriault, make sure you are looking at YOUR Joseph Theriault, not the listing for his father, grandfather, cousin, son or grandsons, all of whom may have been named Joseph Theriault. Yes, researching Acadians and other French-Canadians can be tricky at times.
Once you find a person in the database, you can click on various links to display that person's pedigree chart, descendants chart, a fan chart, a timeline chart, and more.
The Evangeline's Cousins web site offers one very unusual option: you can download a GEDCOM file called BEL.GED. This file contains the entire database and can be used to import all the records into many other genealogy programs. Yes, you can import information about 564,125 individuals into your genealogy program. (I suggest you create a new database first and the import this information into that. Never import data of unknown accuracy into your existing database of proven ancestors!)
Importing more than a half million records just may "stress test" a few genealogy programs. However, if your favorite program can handle a database of that size, the result should be a database that is faster to search on your local computer than any online web site will ever be.
I cannot vouch for the accuracy of the data on the Evangeline's Cousins web site. The information about 5 or 6 of my distant ancestors seemed to agree with the information I found years ago in various books and transcriptions. However, my sample was a fraction of one percent of the Evangeline's Cousin's database of more than a half-million plus entries. I couldn't verify everything. As with all other genealogy information found online or in books, I strongly suggest you independently verify every piece of information you find before you accept it into your records.
I could not find any information on the site about who created it or who contributed all the information. Whoever it was, he or she has placed a huge amount of genealogical information online!
