Robert,
The town of Tynemouth was/is a small town at the mouth of the town. The Township of Tynemouth covered an area a litte larger than the town of Tynemouth. The Parish of Tynemouth covered a wider area including North Shields, Whitley, Cullercoats, etc. The Registration District of Tynemouth from 1837 covered the six parishes of Tynemouth, Wallsend, Longbenton, Earsdon, Horton and Cramlington. The Urban Sanitary District of Tynemouth covered--- stop me, please !
So references to "places" of past times, would benefit from a qualification like town, parish etc, that they perhaps don't need today.
Trivia Angle. I went to King Edward VI grammar school in Morpeth (town). Our sister school was Morpeth Grammar School for Girls, which occupied the site now occupied by the Register Office.
