Something I noticed that was missing from your tree:-
Margaret Holland, daughter of James Angus, surveyor, married John Henry Cox, a gardener, on 28th December 1912 at St Peter, Loughborough.
Both widowed of 60 Derby Road. The witnesses were Joseph Earl Peacock and Lizzie Rose.
I can't find them after the wedding.
One way of finding people on the 39 register is through their birthday. Unfortunately, it means buying the birth certificates, but I have found a few missing relatives by using their first names and birth date. However, a lot of birth dates differ from certificates, often a year or two out or the day of the month is different.

P.S. - In 1915, Margaret Cox of 60 Derby Road was on a list on people eligible to vote as Parochial Electors only.
wow thanks for the information really appreciated and thanks for the tip of the 39 register will give a try with different days in the month, sorry for the late reply.
