This may be of some help:
1911 Census James Waldock (Occupation: Bill Poster, general) born abt.1874, married with 5 of 6 children still living (4th is Thomas aged 6) and his wife Susannah living at Cars Back Buildings, Scotland Gate.
1939 James Waldock (Billposter, light work), born, more specifically, 04 SEP 1873, is now widowed, aged abt. 66 years. Also resident is Margaret A J Smith, born 22 JAN 1897, (now 42 and therefore 24 years younger than James). Margaret’s civil status is given as ‘married’ and occupation as "umpaid housekeeper" a title usually applied to wives. They are living at Victoria Terrace, Bedlington (number difficult to read but situated between 77½ and 78 which seems impossible to me).
There is one other person registered here but that record is closed. However, being listed last suggests that it is a child or a boarder. The latter seems unlikely in view of my next findings.
The 1939 register also records another family Waldock living at 77½ : John Waldock, born 17 OCT 1901 (miner, underground shift work – heavy), his wife Margaret J Waldock born 18 JUN 1905 and one child Lena Waldock (later married Cavoner), born 04 JAN 1935 (year uncertain) now at school. There is one other person registered possibly a child, possibly a boarder but that record is also closed.
As there is no house or dwelling between 77½ and 78 I think it’s fair to assume that James and Margaret Alice are living in at 77½ Victoria Terrace. The present occupier, John born 1901 could well be James’ son – aged 9 years on the 1911 census which would agree with the d.o.b given in 1939.
I hope this is of some help. If you would like the documentation from which I've taken this info let me know and I will send it in a personal message, or, with your permission, publish it here.
