Since my Quick Direct Ancestors from Zennor,Towednack & Saint Ives Emigrated all parts of the World,with a few in Tamworth NSW, Victoria & South Australia. I have a Quick Born Waterford County, Ireland.
Which brings me to answer your inquiry. The Boat was bound from the Fishing Village Dungarvan, Waterford County, Ireland to Breton,only to flounder on Rocks at Cape Cornwall. (Wicca Pool).
Henry Quick 1792-1857 'The Life & Progress' of Henry Quick of Zennor By P.A.S.Pool makes reference of the Tradition that the Quicks of Zennor & the Parish of Towednack are descended of the Irish Mariner Unknown Quick.
Another Publication out of Print & very hard to track down a copy,is for P.A.S.Pool's "The Quicks of Zennor'.
A large entry of Quicks are found in my Ancestry.com Public JENKIN FamilyTree.
Job Stevens 1781-1863 my 4X GGfather,Prior Entries are Stephens of Saint Ives.
Trust this is helpful.
