Mr Brewer used to participate in this genforum, though I don't recall seeing anything from him lately. As always in Genealogy, as soon as something is published, people let you know where you were wrong. Perhaps Mr Brewer was working with the publisher on an update to include any corrections or additional data. Then again, it could have been any Brewer descendant making additions and corrections based on their own research.
