About the location of some clubs.
From Hugh Alexander Kennedy 's "Waifs and Strays": the London Chess Club resided somewhere in Cornhill, the St.George's Chess Club in St.James' Street.

<The late Mr. Elijah Williams, the celebrated Chessplayer.— (From a Correspondent.) — This lamented gentleman was professionally a surgeon, but for many years had discontinued practice. When the cholera, to which he fell a victim, broke out, he benevolently posted a notice on the door of his house, inviting the poor to apply to him for preventive medicines, if attacked by premonitory symptoms, offering it to them gratuitously. On leaving his home for the last time, he asked his wife to give him some of the medicine, as he felt unwell. Unfortunately, the last bottle was exhausted. He walked to town, and was seized with violent pains near Northumberland House, in the Strand, and on the advice of a friend, went to the Charing-cross Hospital for relief. This occurred on the 6th of this month; on the 8th he expired in that establishment. Some of the medical men hoped that the crisis had passed; but Mr. Williams pointed to the blue marks on his nails. He was convinced, from this discoloration, that he would not survive. He has left a widow and four young children, utterly unprovided for; but his friends are raising a subscription for her support. It is hoped that this melancholy case, really worthy of Christian charity, will excite the sympathy of chess-players in particular. We urge the claims of the widow, the more earnestly, because we are personally acquainted with her truly deplorable position. Her youngest child is only eight months old. She is an amiable lady, deserving of aid in her sad bereavement.>

This correspondent, presumably Staunton, is evidently the source for Hooper & Whyld.

What's your source for this?

Here's one of its volumes (post-Williams):

Winter has this:

<An author and dramatist, Knowles edited the Illustrated London Magazine from 1853 to 1855. For a short time, Elijah Williams edited a chess column for the magazine, and on page 141 of volume one (1853) ...>

C.N. 9099

In 1853 Williams was certainly involved, at the start of the column at the very least:

(Cf. the bottom right corner text)

Or even C.N. 9909

Knowles was the general magazine editor. It's not clear who he got to replace Williams, but I doubt he did it himself.

This should make things a lot clearer:

OK, we now know Aug 1853.

<to his end,>

Pretty sure this is also wrong. Likely he only did 3 columns, as documented in the issue.

The rest is hearsay from "uncalibrated" sources.

The complete history of the chess column is outlined.

<THE LATE MATCH BETWEEN MESSRS STAUNTON AND WILLIAMS.

MR EDITOR : At the conclusion of the last game in the recent match between Mr Staunton and myself, that gentleman led me to infer that he should mention in the <Illustrated London News> that the loss of the match was in a great measure to be ascribed to the wearisomeness induced by the long time occupied in deliberating over some of my moves. At the time I did not think it worth my while to take any notice of this threat, as it was quite apparent to me that Mr Staunton was somewhat irritated by his defeat. I do not deny the fact that I did take a considerable time over some of my moves. I was quite aware that I had a Staunton to contend against. It was, however, with considerable pain (chiefly on Mr Staunton's account) that I read the statement put forth in the next week's impression of the <Illustrated London News>, reiterating the complaint. Had the matter ended there I should have passed it over in silence, remembering that those who win can afford to laugh. But when I find the same excuse for Mr Staunton's defeat alleged week after week, I fear my further forbearance may be viewed in the light of a total acquiesence in all that Mr S. has urged upon the subject. Now, sir, I beg to assure you that I took no more time over my moves than did Mr Staunton. During the course of our match I can with truth assert that Mr S. several times took upwards of an hour in the consideration of a single move. Upon the occasion of the second day's play of the final game, and that, too, when there were very few pieces on the board, Mr Staunton actually deliberated one hour and three-quarters over a move. Now, sir, it is well known in Chess circles that Mr Staunton, more especially in match games, is one of the slowest of players, and I can refer to many respectable and high authorities for the truth of this statement, particularly with reference to our late Tournament match, properly so called. I will merely add, that it is principally to Mr Staunton that the introduction of this systematic practice of slow play (of which he so inconsistently but justly complains) is attributed in the London Chess circles. - Yours, &c, ELIJAH E.(?) WILLIAMS.

i) November 1850 - 56 Walnuttree Walk, at the time of his marriage to Mary Hodson (his second wife);

ii) March 1851 - the census finds him at the Hodson family home at 32 Dodington Grove;

iii) July 1852 - Surrey Place, according to daughter's baptismal record;

After his death in September 1854, another daughter was baptised in October and his son in November, the two addresses - South Street and Hope Terrace, South Street, respectively - surely refer to the same property.

But was this Williams's address when he died? Townsend apparently missed his burial record at St. Mark's, Kennington (the same parish as where the children were baptised) which states he was buried on September 12th, and gives the final abode as Outwell Terrace, Paradise Row, Stockwell. The only blemish is his age is given as 43, not 44.
