Some grains of truth may be embedded in this fanciful narrative. Perhaps the inception of the club may have been due to Tonson's astuteness from a business point of view; but at an early stage of the history of the club it became a more formidable institution. Its membership quickly comprised nearly fifty nobles and gentlemen and authors, all of whom found a bond of interest in their profession of Whig principles and devotion to the House of Hanover, shortly to be established on the throne of England in the person of George I. Indeed, one poetical epigram on the institution specifically entitles it the "Hanover Club."

It seems that the earliest meetings of the club were held at an obscure tavern in Shire Lane, which no longer exists, but ran parallel with Chancery Lane near Temple-bar. This was the tavern kept by Christopher Cat, and when he removed to the Fountain tavern in the Strand the club accompanied. Its principle place of meeting, however, was at the mansion of Tonson at Barn Elms, where a room was specially built for its accommodation. The dimensions of this room were responsible for the application of the term Kit-Cat to portraits of a definite size. Thus, on the suggestion of Tonson the portraits of the members were painted by Sir Godfrey Kneller for the bookseller, but as the walls of the room at Barn Elms were not lofty enough to accommodate full-lengths, the painter reverted to a canvas measuring thirty-six by twenty-eight inches, a size of portrait which preserves the name of Kit-Cat to this day.

Apart from its influence on the nomenclature of art, the club is memorable for the additions it caused to be made to the poetic literature of England. One of the customs of the club was to toast the reigning beauties of the day regularly after dinner, and the various poets among its members were called upon to cast those toasts in the form of verse, which were afterwards engraved on the toasting-glasses of the club. Addison was responsible for one of those tributes, his theme being the Lady Manchester:

"While haughty Gallia's dames, that spread
O'er their pale cheeks an artful red,
Beheld this beauteous stranger there,
In native charms divinely fair;
Confusion in their looks they show'd;
And with unborrow'd blushes glow'd."

But the Earl of Halifax and Sir Samuel Garth were the most prolific contributors to Kit-Cat literature, the former being responsible for six and the latter for seven poetical toasts. For the Duchess of St. Albans, Halifax wrote this tribute:

"The line of Vere, so long renown'd in arms,
Concludes with lustre in St. Albans charms.
Her conquering eyes have made their race complete;
They rose in valour, and in beauty set."

To the Duchess of Beaufort these lines were addressed:

"Offspring of a tuneful sire,
Blest with more than mortal fire;
Likeness of a mother's face,
Blest with more than mortal grace;
You with double charms surprise,
With his wit, and with her eyes."

Next came the turn of Lady Mary Churchill:

"Fairest and latest of the beauteous race,
Blest with your parent's wit, and her first blooming face;
Born with our liberties in William's reign,
Your eyes alone that liberty restrain."
