Little is known of this painter, but he/she seems to have been active in Cornwall during the early 1900s. A correspondent has been in touch (2022) advising us of a watercolour in Newlyn School style by J Le Breton, purchased by his grandparents from a gallery in Penzance in 1912. Further paintings, entitled 'Newlyn Harbour' and 'Quiet Harbour' can be found on arcadja.com. There is also an image of a painting by this artist of St Michaels Mount, described as 'of the 19th century English school'.

We were contacted in 2024 by a correspondent who is in possession of a watercolour by this artist, purchased in 1970 in Bideford, entitled 'Fishing Fleet'. 

We would welcome further information on J Le Breton.
