Don't waste your time. This book contains what appears to be valid genealogical data, but is not. The dates sometimes don't make sense, For example, these children in one family: 1509-1575, 1513-1574, 1513-1574, and 1515-1574. A set of twins, and, in all 4 adults who died so close together? If I were printing that, I would also find out and include the reason. And some of the places are troublesome, as well. I was particularly struck by the children who were born in "Shropshire, Bedfordshire", two separate counties far from each other in England. Without attached proofs, which I didn't see, I don't trust any of this.
