Brain-Teaser 491

From The Sunday Times, 25th October 1970 [link]

Each of the five families in Admirals Walk comprised three boys; one of the boys in each family had the same christian name as the surname of one of his neighbours, and no boy had the same christian and surname.

The three christian names of Mr. Arnold’s three sons all had the same initial as the surname of Lawrence, who lived opposite to Benjamin Thomas.

Mr. Gordon’s oldest son had a christian name with the same initial as Clement’s surname. Clement’s father played chess with Jasper Lawrence’s father.

Mr. Oliver was Arnold’s father’s business partner. Godfrey had measles. Mr. Oliver’s oldest son had the same christian name as Crispin’s surname, and also the same initial to his christian name as Arnold’s surname. Arnold lived next door to the man whose son Oswald played truant from school with his cousin Hector Lawrence, until Oswald’s brother Walter, a school prefect, caught them.

Gilbert and Oscar had red hair.

Oliver was in Borstal. What was his surname?

When originally published the condition relating to Mr. Oliver’s sons was given as:

Mr. Oliver’s oldest son had the same christian name as Crispin’s surname, and Mr. Oliver’s youngest son had the same initial to his christian name as Arnold’s surname.

However a correction was published with Brain-Teaser 493 stating:

It is regretted that in para. 3, line 7, “youngest” should have read “eldest”. However, as the correct initials of these boys can be proved independently and most solvers gave the correct answer, this answer will stand.”

I have made the correction in the puzzle text above, although instead of just changing “youngest” to “eldest”, as we are already talking about Mr. Oliver’s oldest son, I used “and also”.
