Can see your problems.....sorry , no clever solutions !
But ......... Sarah nee Dodds, born circa 1812/13 ( 48 on c61, 58 on 71), has a dtr in 1848 within Tynemouth Reg District, to a Mr Ridley. so aged 35 by then.
Sarah is young enough for Mr Ridley to have been second husband with Joseph P Morton, her third, and Mr A.N. Other number one .
Any such marriage cert or BMD index might show her as Sarah nee Dodds, formerly "

??".. But she could easily have married before July 1837 ( she would have been 24/25 by then ?)
Sarah born in west of the county, brother ? William Dodds, the ship's carpenter, born in Wallsend, circa 1820/1 in the east of the county. So maybe Sara moved eastwards, into Tynemouth territory,(Wallsend in Tynemouth BMD jurisdiction) after she was 8 or so !
So maybe her marriages, all of them, were within Tynemouth Reg Dist ( But Tynemouth's border with Newcastle City Reg District was close to west end of Wallsend.
Whellans Trade Directory for Northumberland and Durham, published 1855, shows Sarah Ridley as publican in the SHIP, Howdon Panns.
It also shows a James Twizell as landlord of the Half Moon.
