In a former issue of this journal I presented evidence to suggest that in or about 1686 William Talman was concerned in the rebuilding of Holywell House in St Albans for the then John, Lord Churchill, afterwards first Duke of Marlborough. The chief clue was a payment of £500 to Talman entered in Churchill’s account with Child’s Bank, a sum not sufficient for a complete rebuilding even of a small house such as Holywell was, but perhaps representing an advance or intermediate instalment. This one payment, for which the actual purpose was not specified in the account, together with two smaller ones in the following year to craftsmen of the King’s Works and some independent evidence that Holywell was being remodelled at this time, were all the evidence then available for what appeared to be one of Talman’s earliest country house commissions; and as such it has made its appearance in the latest edition of Colvin’s Biographical Dictionary of British Architects.
