_Catharine Barton_ (Vol. iii., pp. 328. 434.).--A correspondent has asked what was the maiden name of this lady, the widow, as he calls her, of Colonel Barton. I have a note of Charles Montagu, writing of her as "the beautiful, witty, and accomplished Catharine Barton," and have marked her as the daughter of Major Barton, but cannot find my authority. What follows is hardly likely to be of use to your correspondent, though it may, possibly, suggest to him a channel of inquiry. The Rev. Alexander Chalmers married Catharine Ekins, a niece of Mr. Conduitt, to whose daughter he was guardian after her father's death. Mrs. Chalmers had a brother who was rector or vicar of Barton, Northamptonshire. Alexander Chalmers was rector of St. Katharine Coleman, London, and of Burstow, Surrey; clerk of St. Andrew's, Holborn; chaplain to the forces at Gibraltar and Port Mahon: he died in 1745, and was buried in St. Katharine's: his wife was of the family of Ekins, of Rushden, in Northamptonshire. On August 12, 1743, Alexander Chalmers writes, "This will be delivered you by my cousin Lieut. Mathew Barton," probably his wife's cousin: in another letter he speaks of Miss Conduitt as his wife's cousin. Mr. Conduitt died 23rd of May, 1737, and his widow's "unexpected death" seems to be alluded to in a letter in 1740. DE CAMERA. _Alterius Orbis Papa_ (Vol. iii., p. 497.).--This was not, as A.B.'s informant thinks, a title of honour bestowed by any Supreme Pontiff upon any Archbishop of Canterbury, but a mere verbal compliment passed by Pope Urban II. upon St. Anselm, when the latter went to consult the former at Rome. The words are those of Gervase, the monk of Canterbury, who tells us: "Tantam ejus gratiam habuit, ut eum (Anselmum) alterius orbis papam vocaret (Urbanus papa)."--Ed. _Twysden_, ii. 1327. Eadmer, who was with the archbishop when he went to Italy, gives the following as the Pope's expressions: "Cumque illum, utpote hominem cunctis liberalium artium disciplinis innutritum, pro magistro teneamus et quasi comparem, velut alterius orbis Apostolicum et Patriarcham jure venerandum censeamus."--_AA. SS. Aprilis_, t. ii. 886. D. ROCK. You have not told us the origin of this title. I have just been reminded of the omission by the dedication of _Ludovici Cappelli Commentarii_, Amstel., 1689, which is-- "Wilhelmo Archiepiscopo Cantuariensi ... alterius orbis, sed melioris, Papæ."
