Just to close out the story if anyone is interested.
The lady on Ancestry never got back to me so I eventually bit the bullet and purchased a copy of the birth certificate on Scotlands people.
Got it through and we are indeed related, however, it was not my Grandfather that was the father but his brother.
Sadly, when I met up with my siblings recently and told them of the story they all seemed to know and also told me that the brother was shipped out to America when his parents heard he had became a father where he set up home, got married, had children, joined the navy all before drinking himself to death.
Still, at least the case is closed for me now
