This book gives no sources.
This book is characterized by sloppy editing. Never have I refuted a source so often by citing a contradictory assertion on a different page of the same source, e.g., one birth date for a person when listed with their parents, a different birth date when listed with their spouse.
This book appears to make lots of typos. Many dates are inexplicably different than the records. Either lower quality sources were used, or typos were made. Since no sources are given for the information presented, we can't tell.
This book exhibits a disturbing lack of precision. (For example, lack of birth and death locations, marriage intentions represented as marriage date, naming of spouse with no other identifying information, invalid or dual dates with no explanation.)
This book is hard to use due to the lack of a numbering system. It is arranged by generation, and by birth order, but by the fourth or fifth generation, there are often people with the same name whose father had the same name, and navigating gets very difficult. There are three indexes: Kelley, O'Killey, and non-Kelley names.
This book appears to make quite a few mistakes in the genealogy presented. It reminds us that it is easy to write something down on paper, but that doesn't make it true. People looking for a reference should pass this by. It should only be used by people willing to double-check the facts. --Jrich 14:43, 30 May 2015 (UTC)
