by John Marshall, Royal Naval Biography — Layton… (1823)
“ This officer was made a commander on the 10th June, 1825, in consequence of the death of his brother, Lieutenant Thomas Layton, R.N., who had then been recently murdered by a horde of pirates in the West Indies, to suppress whose depredations he was then using every gallant and zealous effort. Commander Layton is now, we believe, employed in the coast guard service, at Killybegs, Ireland. ”
