In his book 'Beyond the Bar' Barrie Youde lists a J CORRIN as licensed (as a Liverpool Pilot) in 1833 but died the same year. This is patently incorrect since the Liverpool Mercury of 12 March 1866 carried this obituary :-
CORRIN - March 11, at his residence 126 Duke Street, aged 54, Mr John Corrin, master of No 9 pilot boat. The interment will take place at Smithdown Lane cemetery on Wednesday morning next at half-past ten. Friends will please accept of this intimation.
Youde also has in his list of Liverpool Pilots :-
CORRIN R - born 1831, licensed 1856, retrired 1882, died 1896
CORRIN W - born 1822, licensed 1845, retired 1869, died 1889
Hope this is of some use.
