Yes a really informative entry, if you look at the 1939 entry you are given a short history of the family in one document.
Claude A Chatteston, born 17 Jan. 1913, a coal miner (Hewer, i.e. he worked on the coal face) was living with his wife and children. Ida Chatteston, born 14 Aug. 1914 his wife, Iris C Chatteston, born 24 Aug 1934, daughter, Claude A Chatteston, born 2 Jan. 1938, at 43 Medway Street, Nottingham. At some time in the future the father Claude possibly died or his marriage failed and his wife Ida remarried, Mr Brierley (possibly Claude Brierley (mother's maiden name Derrick birth reg. Sep 1913, Nottingham, 7b, 740) but there are other possibilities) or took his name. The NHS were informed of the change of name on the 11 Jun 1946, as the children were both under 21 they adopted the new surname as well after their mother's marriage.
The daughter Iris C, married Mr Read in 1957 and the NHS were informed or registered her new name on 12 Dec 1957.
From this entry it is possible to quickly check for Claude, the father's death between 1939 & 1946, mother Ida's marriage in 1946, daughter Iris' marriage in 1957.
It is also not too much of a leap of faith to think that son Claude may have followed his father into the mining industry, and possibly married in the early to mid 1960s.
