There is ample warning from professional genealogists to check and cite the source of your records correctly. Therefore, I try to find my own records as much as possible rather than using someone else’s tree for the same family. It is rather frustrating when you find that they are for the main part accurate but I still feel better about at least checking things. You run into problems most times because of naming patterns. The son being named after the father for instance. That can also be a help because names tend to run in families. There is also a problem created by indexed records which may contain errors through transcription and the interpretation of at times illegible handwriting.
Like most people with the Beauchamp name in Quebec, I knew the pioneers in the family were Pierre, Jacques and Jean. Comparing trees, I saw that I had the wrong line going fairly far back. At that point I had to start checking and double checking to see how many people had the same line going. That would be the line connecting to Damase my great-grandfather. So I would use them as a framework and check each person as I went. Then I hit the Joseph’s in the family. Not fun. There is the name they were called and the name they were baptized with. I was thrilled to see a whole family of voyageurs. I had found records of two brothers I know are in my family, Jacques and Pierre Beauchamp who were voyageurs. Many men had to supplement their income by transporting goods and furs along the rivers of New France. They were two generations back and one of them was called Damase.
There are, of course, many resources for Quebec genealogy which you can find at Cyndi’s list. Ancestry is so good at joining things up for you, the index and the original. That is a help because if you are able to actually read the original you will get extra information. So, by looking at the orginal baptismal records, I found out that the two Joseph’s were called by their second names of Theophile and Isaac . Then I started cross-checking with the records at PRDH from the University of Montreal. That is a paying site as well but with a little information you can save some money by looking for the union or family of two known ancestors. They have been kind enough to list the couple with their parents, date and place of marriage along with their children’s information. That costs 17¢ (providing you know who you are looking for). Pretty cool! Then you can go from there.There is also a tree at Nos Origines, another site that is fairly well done. So you can see I am right in the middle of it now. What fuels me? The history of the place and times my ancestors lived in and knowing I am part of that. And the memory of my grandparents.
