I think my dad was asked for some information for this first book. Most he saw in the book was accurate according to our line, but there were some errors he noticed later. Not many, but the information, like other sources needs some back up and observation.
There were a few Tuttles of the same age and name that were not the same people. These sometimes were mixed up. I see on Wiki the same errors. So frustrating and I hate to think we are just duplicating the errors.
Hope we all check and keep an open mind when we are doing our charting.
