Just found your message after being on holiday.
George Henry Randolph Havercroft was a business partner of my husband and they had an engineering firm in Peel for many years.He is probably about 65 plus now, it was his father (also a George) who was the schoolteacher at Ramsey grammar school, he died in the late seventies I think.
George junior latterly was coroner for Middle in the Isle of Man he married a Philipino girl, "Luce" and has now retired to the Phillipines to live.
There is a G.H.R.. Havercroft in the phone directory, this we think is the number of George's transport firm, now we think run by his son(s) from his first wife.
Sorry I don't have a contact telephone number for George, we met him in the autumn when he was back in the Island doing some business
