MissScarlett: Appears to be a distinct paucity of biographical detail for this player, although he was fleetingly active on the London chess scene for a number of years:
<Gaige (1987)> confirms that he died in London, but I couldn't find any death notices in the British press. As for chess magazines, 1877 seemed a particularly unfortunate year to die. The <Westminster Papers> was, apparently, the only British periodical
in circulation, and I don't have access to it.
The Era, July 28th 1861, p.5:
<MR. VALENTINE GREEN, an Amateur whose name and reputation are well known in Chess circles, has just arrived in this country, after a long absence in India. On his arrival, Mr. Green immediately intimated to the Managing Director his intention of competing in the grand Tournament at Bristol. Mr. Green is at present in the North, but will shortly arrive in London, where his presence will, no doubt, be a source of much interest to Chess society. We are pleased to hear that Mr. Green has lost nothing of his old enthusiasm for the noble game, and that it is his intention to publish a little volume, recording his Chess experience in India, together with the games he played there with natives as well as Europeans.>
Edochess gives Green's last recorded chess before his moving to India as c.March 1856. Returning in July 1861 means that he could have been out of the country for up to 5 years.
Bristol Daily Post, September 9th 1861, p.2:
<Foremost in the list we find the Grand Tournament, in which some of the strongest players in the world will compete; the names already entered comprise among others that of Boden, reputed to be the strongest of English players. Kolisch also, who aspires to an equality with Morphy, Valentine Green, who has just returned from his encounters with the great Indian celebrities, and last not least, that of Paulsen, in some respects the most wonderful player who ever lived.>
This was printed the day before the Bristol event began; for whatever reason, Green didn't show and Wilson (mentioned as taking part in the Minor tournament) took his place: Game Collection: Bristol 1861
