This genealogy is well indexed in several categories. Births, marriages and deaths were moderately researched for the family of Eli Cooley Bliss (No. 1705 in this geneal.) and were found to be accurate. For the purposes of serious family research, this book is slightly above average in that the author included some snippets of records, though most records are not well identified. For serious researchers, this book IMHO can be considered of above average accuracy and considered an excellent source of information for further documentation.
