Arthur William TAYLOR of Harwood Island, Lower Clarence River NSW (born Arthur Button, Brighton, Sussex, England 18 Nov.1882 - but took the name of his stepfather William Henry Taylor), served as 3rd officer on the 3-masted sailing vessel Cassius in 1903 (from an item in the Clarence River Advocate 11 Dec 1903) and second mate on the barque Helen Denny in 1904. The Cassius seems to have been trading between Table Bay (Capetown) and Valparaiso (Chile) via Sydney; the Helen Denny mostly taking coal from Newcastle NSW to ports in New Zealand.
My question - is Arthur included in crew lists for any other ships? I'm not even sure where to start looking. For example, his service on the Cassius is unlikely to have started before 1903 because the ship was only bought by its new owners (James Ritchie, Dundee) in that year - it was previously named the Kilmory (owned by Roberts, Glasgow).
He immigrated to the United States in 1907 where he married in 1911, naturalised in 1915, and lived the rest of his life, so I would not expect to find any crew list entries after 1910 at the latest.
An item in the Clarence and Richmond Examiner 27 Nov.1897 indicates that at that date he was still at school - as an entrant in an essay competition, and he was at home in January 1900, as a witness at his sister's wedding (named on her marriage certificate).
So the search is at least narrowed to a period from 1898 or more likely 1900, to 1910 at most.
