Copied from Vaughan's post above, for a point of reference on the "3 informants" that Carpenter was saying, in his article, were on the sea by 49/50...well, 2 of them. Not sure who the third was (yet), or if I misread something.

* Edward Robinson - born 1834 - to sea 1846
* Mark Page - born 1835 - to sea 1849
* James Forman - born 1844 - to sea 1856.
