hello david, you write about the Claverdale going missing in the pacific, date unknown. My G. Grandfather, William H Lambert was a master in the Dale Line, owned by Sir Philip Laing of Sunderland. One of his ships was the Ferndale, his regular run was with iron ore from Bilboa to the Tees & Tyne for the Consett works. Perhaps the Claverdale was originally a Dale Line ship later sold. It would be interesting to hear from anyone who has ancestors who were crew members with the Dale Line in the late 19 c. My other shipping interests are with the Prince Line, owned by Sir James Knott. Regards, Derek Lambert.
