I feel that the main part of researching family history is the satisfaction of knowing that you got there yourself with a lot of hard work and fun along the way. I do not post my tree or use information from other trees posted on public sites, because from the ones that I have seen, there are many that have been posted that contain errors. I am always happy to share the information that I have with genuine people who contact me. At least I know that I am giving them accurate information.
When I have hit a brick wall in the past, there are many on here that have offered valuable advice and help to overcome it. I don't understand some peoples need to post
any suitable person in their tree just to say they can go back twelve generations. Isn't it better to go back four generations, knowing that it is accurate and with the satisfaction of knowing that you got there with your own hard work.
If I found an error in my work, then I would want to be told about it. Likewise in the past, I have tried to tell some people of their errors in public trees, only to be met with indifference.
On one public tree, my great grandfather ended up getting married and passing away in America. He had American descendants. I did try to point out to the tree owner, that in fact my great grandfather never visited America, never married in America and certainly never died in America.
With Christmas coming, I must pop down the village cemetery and put some flowers on his grave.. They still wouldn't listen
