Pat,
Your Man of Mystery...... So Richard died in December 1851. at 7 Claremont Place, Newcastle
Nine months earlier the 1851 census showed the residents of that address ( 2405-468-24) to be William Shield, a publisher and print seller, and his family. No sign of any Spoor !
You wrote that the "informant" D.D. Main lived at 13 Elsdon Place.
On C1851 a David D Main lived at 13 ELDON STREET
(2405-457-3). He was Scotland-born was was "Secretary to the Whittle Dean Water Company"
House numbers 1-9 were Eldon Place, numbers from 10 upwards were Eldon Street ( DD Main and family were still there in C1861 -3818-28-5-, when it was 13 Eldon Place.
You mentioned Spoor roots in Whickham. I noticed Charles Spoor on 1861.. was born Whitburn.. Barbara's info shows the Spoor duo to be in Whitburn on C1841.
That C1841 showed Charles to have been born in Co Durham, but Richard not !
Trivia Angle... you mention folk moving from Whickham to Newcastle to etc... but there were probably many similar opportunities to be had in Whichham area, without the need to cross into Newcastle.
