Just some notes re: the Falcon-Lang family- I looked into them just because the name caught my interest, and from what I could find it seems the only marriage record for Stephen Falcon-Lang was 1962, his wife being listed as 'Betty M. A. Falcon-Lang' or alternatively 'Betty M. A. Rao', or 'Falcon-Lang Rao'. I don't know what this implies. All five Falcon-Lang births I came across gave the mother's name as 'Ellis', including Howard J., starting with a daughter, Orietta, b. 1962; Stephen Falcon-Lang's death notice here-
https://announcements.johnstonpress.co.uk/obituaries/sleafordstandard-uk/obituary.aspx?n=stephen-falcon-lang-basil&pid=182661095 - also indicates, with widow Betty, an eldest daughter Sheila; she wasn't amongst the births I found, so possibly daughter of his wife from a first marriage? Similarly, two sons, Ken and Howard (as above) mentioned, but the elder of S. Falcon-Lang's sons appears to be Stephen Robert (whom, it seems, also died 2012); as his father seems to have used the name 'Basil', perhaps he too uses another name, or the 'Ken' mentioned is also a child of his wife's hypothetical first marriage. I couldn't find any marriages for a 'Betty M. A. Ellis' to a 'Rao', but perhaps this occurred outside the jurisdiction of my usual records.
I was unable to locate the birth of a Stephen ('Basil') Falcon-Lang, under that name, as Stephen F. Lang, Stephen Lang, or Stephen Falcon, within U.K. birth records around his birth date, which is of course corroborated by the death notice. I couldn't find any mentions of him online anywhere either, save an indication on findmypast that he was a company director; Companies House however had nothing on record.
