Jillaine,
I'm one of the guilty parties who includes everything I can find, whether a real source or just information somebody decided to put on the internet just because they know how to upload or enter things.
Maybe it's an excuse, but most of the profiles I work on are very challenging and I am not able to find what I have now learned are good sources. I figure that if I at least throw up there all the information I have found, and always include the statement the "A more reliable source for this information is required." it might help somebody else somewhere down the road who has more capability than I do to find a better source. In some cases, the multiple private (and unsourced) trees have variations in spellings or dates or places that could point to other possible ways to search. I'll use what appears to be the source of information most likely to be correct (in my uneducated opinion) for footnotes and dump the rest into the "See also:" section.
I guess my modus operandi here is that if I can't dazzle them with brilliance, I'll baffle them with ... umm ... err ... sorry, but as a respectable grandmother, I don't know what I can baffle them with. I would treasure your opinion of whether I shouldn't include all this extraneous stuff. THANX!!!
