And, in this case, be cautious. It's not just the number of sources listing one thing or the other-- it's important to understand the types of sources and their reliability (or lack thereof).
For example, of the above list, I would not rely at ALL on the Millennium File. Search g2g for it and you should find my discussion of why this is a very bad "source" to be avoided at all costs.
AGBI is also pretty derivative. And even US, New England Marriages Prior to 1700 should be used as a guide to sources, not as a source itself.
