I'm wondering if we could be loosely connected. My father, James Gray, was born in Prestonpans and his mother was called Mary Fraser. Her parents were Janet McKinlay, who married James Fraser of Prestonpans. (I have the dates if you’re interested). Janet McKinlay’s parents were, according to her marriage certificate, James McKinlay, who was born in 1818, and died in 1876, and Isabella Pryde. Isabella’s parents were William Pryde, a collier, and – it looks like – Ellen Kerr, on Isabella’s death certificate. Does that tie in with any of the Prydes you have, and if so I'd love to see whatever information you have.
