Is all the Pitre info on wikipedia / wikitrees a good source?
As with so much on the internet, people are trying to make info accessible. Many Pitre lines are appearing from a variety of sources, and many include my own writings lifted in entirety. It would be courteous if those sites included an acknowledgement, but not all do. My best advice is to do as much of your own research as you can. If you’re interested in the most up-to-date Pitre info, then The Pitre Trail should be at the top of your list.
