'In quamcunque domum introeritis primum dicite: paX sIt hVIC DoMVI Tam solenni præcepto, tempestivo voto Subscripsi introiens C. W. RECTOR, Julii 28. Anno dicto.'[23] The inscription is not a little characteristic of the gentle, peace-loving nature of Christopher Wren, and the quaint conceits in which the wits of the time delighted. This form of chronogram was one which he frequently used. His second daughter, Susan, was born in 1627, and as she and the 'second Christopher' clung closely together in after life, and the others are never mentioned, it seems likely that they two were the only survivors of the seven children. Christopher was a very delicate, weakly boy, who early gave promise of brilliant abilities. No records say when Mrs. Wren died, but various things seem to show that she died when her children were still very young. Dr. Wren had been one of the King's chaplains in ordinary since 1628, and so well did he acquit himself that when his brother the Bishop resigned the deanery of Windsor and the registrarship of the Garter, the King appointed Christopher to the vacant post. It was an appointment which suited him well; he took up with equal energy his brother's work, of arranging the documents and records, and continuing the history of the Order. Two autograph letters relating to this are preserved in the 'Parentalia,' one from the chancellor of the Garter, Sir Thomas Rowe:-- 'Reverend Sir,--I had wayted on you before this tyme, but that I have been punished with Lamenes, both for my owne advantage to learne of y^u and to acquaint y^u with some orders I have received from his ma^{tie} and to give y^u ye summe of ye last chapiter as I conceived it.' [GARTER RECORDS.] Sundry particulars follow, and he promises a record of the members of the Garter from its foundation. The King, he says, is anxious that every 'chapiter of the Order' should be fully recorded. Sir Thomas asks for 'the papers of Sir John Fynnet' in order to send them to King Charles, 'who is very curious of them.' 'On all occasions,' the letter concludes, 'I shall be glad to give y^u ye testimonye of my desire to be esteemed and to be y^r affectionate friend to serve y^u, 'THO. ROWE. 'Cranford, 9 Jan. 1636 (O.S.)' The Dean's answer comes promptly:-- 'Jan. 10, 1636 (O.S.)
