· To Charlotte, Queen of the United Kingdom of Great Britain and Ireland : 1 autograph letter signed (copy?) : 14 Sep 1803 : (MISC 4149) : 1 page (double sheet) : from Brentford : begins, "Having so repeatedly expressed your Royal condescension on similar occasions, I am encouraged to hope for your Majesty's gracious acceptance of The Guardian of Education . . . ." Definitely in Trimmer's hand, but perhaps a copy she made for her own purposes; there are no clear signs of this manuscript having been delivered.
· To Elizabeth La Touche, orphanage and charity school headmistress : 1 autograph letter signed : 12 Oct 1801 : (MISC 3926) : 2 pages (double sheet) : from Brentford : begins, "I certainly have not sufficient personal knowledge of the woman I lately had the honor of mentioning to you as Matron for your benevolent Institution . . . ." Mounted in the Agatha Hogsbottom autograph album. Shelved with oversized manuscript volumes.
· To "Sir" : 1 autograph letter signed : "Friday Evening" [1780?] : (MISC 4101) : 2 ¹/₄ pages (double sheet) : [no place] : begins, "I believe I now perfectly understand you, & think I can manage the matter; but do assure you there will be a great impropriety in procuring a recommendation from that quarter at present, as the Book should be presented to the Queen, before it is published." Someone, in what appears to be a later hand, has written "1780" in pencil at the top of the first page of the letter.
Charlotte, Queen, consort of George III, King of Great Britain, 1744-1818, addressee.
