Joseph Marshall was a professional rower.
Bells Life (Jan 1878) reported in their review of 1877:
The early days of April were not marked by any great stir in the rowing way - in fact fourteen days of the showery month had been allowed to elapse before before a match of the slightest consequence took place. It was not until April 14th that the professional element of the rowing world began to stir and the scene of action was the coaly Tyne , where within the space of four days, which included Sunday, no less than four races were set down in the in the list of fixtures for decision. Firstly on the Saturday, J. Emmett and Joseph Marshall rowed a mile and three-quarters on the Tyne, in open boats for £40. It was a very easy matter for Emmett, who won with a lot in hand, his opponent being unable to keep his boat straight.
