    Note 9 Jun 1795 
    Cecilia wrote a letter to her mother saying …
    We arrived safe here yesterday evening after an amazing long journey as you know & faster even than the mail—we were married immediately, stay here all today & set out on our road to Llewesog Lodge tomorrow.


    Hester Thrale’s reaction to this in Thraliana was …
    ;Oh Lord! Oh Lord! Mosty & Cecilia are run away to Scotland sure enough, and here is Mr Piozzi in an Agony about his Honour wch he fancies injured by the step, Susan & Sophyare in Care for the Money which they unjustly fear is endanger’d; Miss Thrale behaves best, & I suffer most—on Acct of her Health & Youth & Inexperience—Oh my poor Cecy!—for the 1st five Minutes I knew not but Drummond might have tricked her off with him pretending to be the other: but No, She is in safe & honourable Hands, and happy with her Dear Mostyn at Llewessog Lodge, where all seem rejoyced to receive & court her Attention.—This Business then is happily over, & I might sleep if Nervous Complaints did not hinder me—for now the other Girls are kind & good, & stuff Cecy, so do I, with bridal Presents; and nobody is otherwise than happy & content.

    Fedele & costante, felice e contento as my master says.
    'Fedele & costante, felice e contento' translates as 'Faithful & constant, happy and content'. 
    Note 17 Jun 1795 
    She wrote to her mother, from Llewesog, that she had been…
    Frightened into fits on her wedding night, and that her husband had kindly and considerately got Dr. Haygarth to prescribe for her at Chester. I am got quite well now & am learning to behave better & an only as usual not to hurried & flurried but left to myself by Dr. H’s orders & then I shall soon be as good as he himself could wish.
     
    Note 11 Oct 1796 
    Her mother wrote in Thraliana about an alleged illegitimate child sired by Mostyn …
    Cecy Mostyn is a foolish Girl, & cannot rule her own Household — all our unfashionable Neighbours cry Shame! to see Mason her Maid with Child by the Master of the Mansion & the Gay Mistress protecting this Partner in her Husband’s Person because it is the Way She says; & all those who understand genteel Life think lightly of such Matters. When I offered to speak my antiquated Sentiments upon the Subject, She forbid me (smartly) to say another Word about it; & told my Maid that if Mrs Piozzi plagued her any more concerning such Nonsense She would leave the House into wch She never came to say the Truth except for mere Conveniency.
     
    Note 12 Oct 1804 
    Her mother wrote in Thraliana of Cecilia's miscarriage of a daughter after falling from a horse …
    Cecilia Mostyn has been here on a Three Days Visit & made herself as it appeared to me, studiously agreeable. cecy complains of her Husband grievously, accuses him of gross Avarice and rough Behaviour—scruples not to confess her dislike of the Man & her Resolution to live with him only till The Boys go to School: yet something says to my heart that half of this is Fable, & spoken with Design of some sort to dig out how far I should grieve at, or resnt his Treatment of her if it was absolutely & truly what She represents.


    I listn’d however with Expressions of Wonder only, & just such Indignation as one could not avoid—Cecy is false as Water— and since She told Mr Mostyn long ago that I wished his Neck broke when such a word has never cross’d my Tongue—what will she not say now? I do not like a Tête a Tête with any but Truth-tellers—& what this fashionable Lady says, must be taken with a Grain of Salt.

    The worst is I cannot sleep since the Visit—such staring tales has She related—& of poor Susan too!! Who can believe as fast as Cis can talk??—
