Hi Bob, Jan, etc. Though I cannot comment directly on your William CAINS' origins, a link to Dorset may not be unusual. My gggf Robert Joice SQUIRE married 15 Aug 1802 at Alverstoke to Martha BOUND appears to have been baptised 17 Mar 1774 in Winterborne Zelston, Dorset, as Robert Joyce SQUIRE, s/o Thomas SQUIRE and Ann SHEARING, who married 17 Jan 1762 in Winterborne Zelston. So some time between 1774 and 1802 he moved from Dorset, probably due to the dockyard expansion between 1760 and 1800 mentioned by Prince Edward in "Crown & Country". This is probably the same time frame that William CAINS could have made a similar move, as you suggested. Was William connected with the Navy Dockyard? I have no occupation for my Robert, but his son Edmund SQUIRE was a Warrant Officer in the R.N. and apparently highly regarded. He died on 12 Feb 1845 of sunstroke in Mauritius (probably should have been wearing one of the straw hats his family made for the Navy! - these details provided by his grandson, my greatuncle, Henry William Squire WILLCOCKS in a handwritten document about his family dating from about 1915.) Hope this helps Regards Martin Willcocks Taylorsville, UT, USA.
