The Llewellyn Batten story:

Llewellyn Batten was born 22nd April 1866 in Coppethorn, Poundstock, Cornwall>

He appears in the 1881 Census, as Boy 2nd Class, aboard the reception or training ship HMS Royal Adelaide at  Devonport.

He is known to have married Selina Ellen Carpenter in Portsea, on 13 Sep 1891.

It is not known where and when he served, except that in a letter dated 3 Jan 1917 he reports  that he had been aboard HMS Queen Mary, and as she was blown up at Jutland on 31 May 1916, it must have been before then (unless he was one of the 9 survivors).  The letter refers to the wreck of his cutter, and attached to the letter are its registration document. The cutter was the Eagle, number P45 in Portsmouth, and it had been wrecked in a gale in 1915???.  His  letter was sent from HMS Princess Margaret, a liner converted into a minelayer/minesweeper, which carried out duties along the East coast of England during WW1.
