IF that list is true
There ain’t no “if” about it. Those references are what’s called primary source records. One must appreciate the difference between primary, secondary, and then even less reliable sources. An original signed paper copy of someone’s birth record is considered a primary source document. The next census record on which that person’s name appears with his or her parents is NOT a primary source – it may be considered a secondary source. Census takers were sometimes careless, lazy, not all that well educated, or just plain didn’t understand the accent of the person living at a given address, and took the information needed for the census form as best the census taker could understand it. And then there’s the entry in the family Bible, added 50 years later by some 3rd or 4th generation descendant, with no sources at all – just a listing of who married who, and who was born to who. It may or may not be even close to accurate – with no way to know, short of access to primary or at least secondary source documents.
The list of 72 categories (a few of which are actually duplicates of others) contains primary and secondary source documents, often thanks to FOIA requests directly to the government offices holding and promoting these views. Anyone that hasn’t seen those primary and reasonably reliable secondary source documents is woefully unaware. I’m more than a little surprised that, particularly among this group, the question of “if” would even come up.
