Hi Suzie, I lived in Renfrew for my first 23 years. Knockhill is near the Paisley Border. In 1841 it certainly would be farmland or woods. Marjory the daughter of King Robert Bruce died there about 1318 after falling from a horse. There was a castle there about that time. JOHN SHAW 1 REDWING STREET BROWNS BAY AUCKLAND NZ.

Hello John Thanks for sharing that information. I'm guessing that it is the only Knock in Renfrew. Have a great day. Suzie
