This is the same George.However, you can pick up all kinds of info (good or erroneous) on him and his son Ralph on the internet and in books.
I have the source of his birth date, from Cutter's New England Families. This may or may not be correct, but is the best that I have found. What is the source for your date?As he ia supposed to have married first before 1588, he was not born in 1582.
Cutter does appear to attribute some of the children to the wrong Catherine/Katherine, but what is listed here is the best synopsis that I have been able to come up with.
George had three wives of which I am aware, none named Sarah.The first is a H. L. Smith, the 2nd Catherine Turner, and 3rd Katherine Unknown (supposed to be a Davis).
Here is the family as I have it (ready for anyone to pick apart)
Wife 1 (pre 1588): H. L. Smith Samuel 1588 Joanna
Wife 2: Catherine Turner b. abt 1567 Thomas Samuel 1597 John Abt 1610 Joshua Abt 1614 Robert Abt 1614 Ralph 1615 George abt 1619
