Thanks all. Someone did some research back in 2018 and discovered the following:
"Official Records in France have now confirmed that Mathurin initially left Le Havre as a 16 year-old mossy, then novice on the 'Carolina' and the 'Asia' between 1834 and 1836, and returned from some long journeys.
However, French Maritime Disarmament Records written by a ship's Master (likely to be Pierre Darmandariz - 'Asia' - Depart Le Havre 8 August 1835 Return 16 April 1837) prove that 'Charles' wisely ended one such dangerous journey in New Zealand on 14 March, 1836, whilst working aboard the 'Asia' at an extremely volatile place for many reasons - 'The Bay of Islands.' The Disarmament notes written by Master of this ship show:- Quote: "Charles Leon Laine deserted on March 14, 1836 in the Bay, having the permission to go for a walk." In addition he wrote: Quote: "MARTIN Felix Edouard aboard with LAINE Charles Leon, followed him, profiting from the occasion." Charles Leon LAINE was definitively "crossed off" French Maritime records on 10 August, 1847. Mathurin was only 18.1 years of age at the time of leaving this ship. Interestingly, his step-uncle, Martin Casper, was Master of a ship from Le Havre with a destination of Bay of Islands - New Zealand from 1839-1840. He also mastered the same ship from Le Havre to South Australia and Oahu from 1844-1847."
