Married to the artist Benjamin Eastlake LEADER, Belle did not exhibit her work, but two attractive watercolours of Lamorna are in the possession of her descendants.

She was born Isabella Anderson to a Scottish lawyer and his Dutch wife, the third of six children. It is believed that she was educated at Cheltenham Ladies College, but it is not known where she studied art, or where she and Benjamin met.

They were married in Glasgow in 1910 and honeymooned on St Michaels Mount. The couple rented the 'Oakhill' cottages in Lamorna until the three dwellings were converted into a home for Harold and Laura Knight. The Leaders then acquired a plot which became 'Rosemerrin', where together they created a beautiful garden. They were two of the most popular members of the Lamorna artistic community. Very sadly Benjamin was killed on active service in 1916 during World War I.
