Thanks everyone for your input, this definitely clears it up for me.
One question though from a novice who isnt used to forum terminology. Can you explain what you mean by "submitted" and "extracted". I am assuming submitted as a Ancestral File and extracted from the IGI.
Sorry I have been missing in action NL but have been working all over Christmas and New Year. Too many lucking people going on holidays!
Sparky, on Family Search, "submitted" entries are those sent in by individual researchers and, therefore, not always reliable. "Extracted" entries are those taken directly from record sources (eg. Parish Records) and are, therefore, much more reliable - There are still at times transcribers errors, but they tend to be pretty good.
