LDS records are pretty helter skelter as most do not cite sources, which are vital.

The other disappointing news will be to discover how rare it is to be able to cross the Atlantic back to one's origin for those who arrived in the New World before immigration records were kept. If the family came through Ireland, it's even harder because many Irish records were lost in fires.

That said, it has been done. I can point at an ancestor from Croy and Dalcross parish and claim him as my own based on birth year and lack of further records after the time the family left Scotland, but there is really no proof at all.

I think what we are really looking for is stories, not names for a tree.
