NettieS's advice and comments are both moderate and helpful. Debra would do well to heed them. The statement about suddenly getting back to the 1500s must have taken everyone's breath away, as it did mine.
Having just read all the repetitive statements, here and other forum, whilst I won't suggest it's a wind-up, the original poster seems to have a very vague and woolly idea of what FH research is, - and an alarming habit of clutching at straws grasped almost at random.
Anyway, if Ms Taylor was her grandfather's mother - then as that's almost certainly not a Jewish surname, and as Jewish descent is traditionally maternal - then, sorry, Debra, that almost certainly rules out being Jewish in any case.
There's not really a "Jewish look", after all, is there. Perhaps there is Arab ancestry in her line? OIr Mediterranean? That would provide the "look" just as well. But I get the feeling that she would not welcome that as much.
Perhaps Trystan ought simply to pm her, and close this thread too, until she has some basic facts for us to use to assist her research. Can anyone put up the e-mail address to guide her to where she can get the certs - less than £10 each, if I remember rightly, and a good investment!
