The portrait above has been shared by a blog reader hoping that someone may recognise the face or have some information to help identify the subject. The portrait hung for many years in the family home of Mary Gillies Rodger (who had strong connections to Lundin Mill and Largo). She referred to gentleman in the painting as "the sea captain". Note the sea in the background with a ship visible to the right on the horizon (detail shown below).
The clothing and appearance of the gentleman should indicate an approximate date for the portrait. He is clean shaven with prominent sideburns – so before the trend for beards that started with the Crimean War in the 1850s. There could be a connection to the Rodgers of Lundin Mill. Any ideas welcome!
