Mary Jane and Annie had two brothers, William John b.1857 and Thomas b.1859, both of whom became master mariners and for two decades were associated with the Hill Line Co. Liverpool. This company, owned by Thomas Pryce of Workington, ran a fleet of some of the largest sailing ships in Britain. On his first voyage William John Jones went with his uncle, Captain Thomas Jones, Ffosygravel, on the brig Pilgrim to Taragona. Later he became second mate on the barque Glendovey captained by John Williams of Borth, on a voyage from London to Rangoon. Soon afterwards he passed as master at Liverpool. William John had gone to sea at the tender age of 12, and went on 19 voyages prior to becoming second mate on the brigs Pilgrim, Glendovey and Ocean Belle, and the schooner Picton, which were all Borth vessels. He was later master of the sailing vessels Ellen Greaves, Spirit of the South, Ethel Anne, Douglas Castle, May Hulse, and then the Bidston Hill, from 1891 to 1898, and the Holt Hill, from 1898 to 1901. The Ellen Greaves was a Caernarvon registered 254-ton brig, with an all Borth crew in 1881. Captain Jones circumnavigated the world many times.
