I'm sorry I can't give you a huge amount of info about the Sinton's that lived in Newcastle, what I can tell you is that my Grandfather (whom I never met) was born in that region. There appears to be some form of silly family family arguement that surrounds them for what ever reason. Basically my father had an Aunt whom lived in Florida, whom he lost track of.

I have however determined a short methodology for spotting a Sinton. It is probably silly, I however have observed this... every Sinton blood male has the "Sinton" hair line issue...

You hide it well Dave http://www.xpressweb.com/~talon/0414_007.jpeg

I'll try and get some more data out of my father you guys want it
