Donna- Bottom Line... IGNORE ALL ONLINE TREES-ALWAYS!
Search only for documents, use mailing lists, message boards, websites (other than online trees) etc. but Never, NEVER, pay attention to ANY online trees ANYWHERE.
You will hear people that proclaim that online trees provide 'hints' - and perhaps they do but most of those hints are as useless as those provided by that blasted shakey leaf and the time you spend verifying those hints could better be used doing actual research rather that following someone else's junkology.
