William Rigg Tenant Farmer of Belgreddan Kirkcudbright

I am requesting help in establishing if a painting THE SPORTSMAN by Painter John Bowie is my relative or not.

The model for the portrait is William Rigg Tenant Farmer of Belgreddan Kirkcudbright by Painter John Bowie 1864-1941 (died Edinburgh) . Painting called THE SPORTSMAN. My William Rigg (1813-1892) was a tenant Farmer in this area at the right time and age of the person in the painting.

The painting can be viewed at http://www.artistsfootsteps.co.uk/artists_a_z.asp?ID=198%20&loadType=2

The Painter lived in Dumfries and exhibited at Royal Scottish Academy. His Old Dock, Jetty and Harbour Cottages in 1904 was exhibited, No 11 in the opening exhibition of the Harbour Gallery, Kirkcudbright, 1957 (in Stewartry Museum file on William Robson).Royal Scottish Academy from Kirkcudbright 1911-1912 and Thornhill 1921.

Can anyone help.

Thanks

Patmotty
