I do geneology, and maybe I can shed a little light on the subject.

I have used all of them..... Though I am uncertain of the validity of FamilySearch. They list my G Grandmother as part of the Glammis Line, And The Lyon Memorial Book Does not, so I am uncertain as to which is accurate.

I would add Published Online Family Tree's like Lynell Arnott's, his is pretty good and it has some of my family on there, so there's that.

You're right, about problems with Familysearch.org entries. I have had to straighten up many mistakes, which I've found. The problem is usually what are called "duplicates." The same person listed several times, each with different ID numbers. Sometimes, Familysearch enters wrong info, which contradicts provable documentation (like the French ancestor, which I mentioned earlier). I've also looked at a particular piece of info, then clicked onto the photo of the original document, only to find that whoever transposed that said info, read it wrong. Still, it is a helpful site. They do have much to offer.
