Does this mean Christchurch, Dorset, or somewhere else? I ask because on Find My Past, they seem to have a transcription of the lightermen binding records, and there is one for a Charles Watson (bound date 1784, if that is any indication of age) from Christchurch.
There are other Charles Watsons in this register, but this one leapt out because of the Christchurch connection. As StevieSteve details, the records at the Guildhall Library should provide more clarity.
I think Christchurch in London, it comes up on London marriages on Ancestry.
There are two records for Charles Watson with the same binding date in 1784, one says reassignment. One is to master also called Charles Watson and one to a different master. This would imply that the first master had possibly died part way through the apprenticeship. The 1770 baptism mentioned earlier was to parent Charles and Elizabeth Watson. There are several other children bapt to same couple in Holborn, but doesn't give Charles snr's occupation on any records.
