I'm after any information about Alexander Duncan and Elizabeth Sinclair who married on the 8th of April 1823 in Rothesay, Scotland. I only know that Alexander Duncan's father was also named Alexander, and Elizabeth Sinclair's father was name John. So far, I'm only aware of three children of Alexander Duncan and Elizabeth Sinclair: Alexander Duncan (Born abt 1829, Rothesay. Not sure when he came to Australia, but he married Harriet Jane Martin in Victoria in 1858), Margaret Duncan (born abt 1826, Rothesay. She married Matthew Coubrough in 1851, Renfrew.), and John Duncan (Born abt 1824). I Descend from Alexander Duncan and Harriet Jane Martin's son, John Sinclair Duncan who married Nellie/Elsie Helene Thomas in 1891, Victoria, Australia- if interested.
