I also am interested in the Duffus of WI. My granfather was a vicar of St Vincent. His name David Alexander Macpherson Duffus born about 1880 or earlier, married Bertha Branch (also a WI name, her father was a Canon). He died 9Fell off a balcony) in the first two decades of the 20th Cent. His farther was James Duffus, and his mother was probably a Macpherson. James Duffus was a planter at Stoke Hall in Jamica. I would be grateful for any further information. John Marten E-Mail firstname.lastname@example.org.
