I have a question on the "Abbot Genealogies" of the Essex Antiquarian and the book Descendants of George Abbot ofAndover.....by the Rev. Abbot's.
There is some difference in dates on many people in these publications. Most are within a few weeks. Abbot Genealogies lists double dates and the Rev. Abbot's (I think) use Old Style in their publication. Is this the major reason for the difference in dates listed ?
I think that both are great sources, however, with the difference of almost 50 years in their publication dates, is one considered to be a more "reliable" source??
