I've used the Hyde genealogy as a source, but I wouldn't call it a respected source. Its author appears to have used original records as sources, but (like most 19th century genealogists), he didn't see a need to cite his sources. But he earns some "trust points" with me for not claiming aristocratic pedigrees (he even had the good taste to not attempt to connect his New England settlers with families in England) and for attempting to document the "female lines" in addition to people with the Hyde surname.
IMO, this book is useful as a basis for a first approximation of a profile or a lineage, but we should try to find the sources that the author didn't cite -- and revise his genealogy where appropriate.
