Hi, my 3rd great grandfather Alexander McLaren was in Demerara from about 1820 to 1850 before returning to Scotland. He owned 2 sugar plantations called La Bonne Intention and Zeeburg. He has several children, including Peter born in 1837. I dont know Peter's wife. He had at least 2 cildren born in Demerara but we believe he eventually he moved back to Scotland. I've no idea if these are the same people, but there arent too many Peter McLarens around.
