Joséph Tréguier is born at Lorient
Between the thirteen voyages on which his name appears, Tréguier's age is listed somewhat inconsistently. But, wherever ages are listed, they all line up to within a few years of what Tréguier's age must have been. In all cases, the Joséph Tréguier listed was born in Lorient between 1739 and 1743. The furthest stretch is the first case. He is listed as ten years old, but if it was the same person, it is more likely that he was about seven years old. Presumably, a young child overstating his age to win a position or a higher wage was not an uncommon occurrence.
In three cases, no age is listed. In the first two, however, he is still listed as a cabin boy earning 6 livres, which is in keeping with the age he would have been on the respective voyages. The third ageless instance is certainly the same person, as it notes the previous ship he had been on.
There is also some variation in name and physical description. The surname is spelled Tréguier or Treguier in most cases. Three times it appears as Treguyer. The given names always include Joseph, but in some cases there are additional given names listed (Jean-Marie Joséph, Joseph-Jean and Joseph René).
He is most commonly described as having a small build and brown or chestnut hair, though in two cases he is described as small with black hair.
In sum, nothing definitively indicates a separate individual. It is quite possible, then, that these are all the same person.
