Whilst browsing the web site Find My Past I happened on Wilfred’s school admission record. He started Willington Council Mixed School (Co. Durham) on 6 March 1903. The School Admissions Book shows that his date of birth was 25 July 1896 and his parent/guardian was Thomas Laws of 4 Clarence Terrace. He had moved up from the infants school. His last date of attendance was 15 July 1910. The reason given for leaving is “age”.
So if my maths is correct he had entered the Mixed School at the age of 6 years and 7 months. He stayed there for the rest of his school life, leaving at the age of nearly 14.
He then started work as a colliery clerk sometime before April 1911 as that is what is shown on 1911 census.
