Hi,
Just noticed this post. Thomas White died in 1852/4 and his wife Elizabeth married their lodger - William Cutler - in 1858. Elizabeth (Cutler, formerly White, nee Whitehouse) died in 1867.
William Cutler appears on the 1841 and 1851 Census with Thomas and Elizabeth (although Elizabeth is shown as Sarah on the 1851 Census; clearly a mistake by the enumerator as her age is the same).
William and Elizabeth appear on the 1861 Census together - still at Temple Street.
Hope this puts you out of your misery!
Regards
