Just an update on this. Since the last message my e-mail has changed, so, be sure to check the new one before sending me any mail.
The second thing is I have found a number of older generations back to 16 hundreds. By this time the family surnames keep changing every generation, apparently without a rule.
The earlier record I have now, on this particular line, is Mathias Jorge married to Andreza Dias about 1670 in Quintã, Cacia, Aveiro. Spite the surname change it is my paternal male line, whose surname has been changed to Dias, then Jorge.
