1889 diary- Lord Chesterfield and Madelina Elizabeth du Bouchet

[Deskman]

In these extracts the diarist is discussing the relationship that led to the birth of Philip, Chesterfield's illegitimate son. I thought I had it understood but I have backtracked and need help with the text

"he would seduce her & the xxxxx xxx xx xxxxxx
(she was a xxxxxx) he succeeded with her
& her life afterwards was spent in obscurity in
London – the “amendment” was declined
Chesterfield must have known of the xxxxxxxx xx xxxxx was cut to the....he behaved most xxxxxx to them "

BTW The amendment was £500 he left her in his will "as small reparation for the injury I did her".
His son Philip married in secret and C. did not know of it until after Philip's death when his widow and children needed help and C 'behaved most ?liberally? to them'

Thanks for any help.

Not sure about this but for the first line:

"he would seduce her & the prettyst of her pupils

She was a dilemma(?)

The "l" is a bit short, though...

[Bookbox]

She was a  duenna, hence the pupils.

[Bookbox]

... Chesterfield the preacher of demurs ...

I'd agree with liberaly.

[Karen McDonald]

She was a  duenna, hence the pupils.

It's obvious when you know. 
I thought about duerma (which was confusing, due to the Spanish verb "dormir" <to sleep>) but duenna didn't occur to me!

That makes perfect sense.

Thank you sami, Karen Mcdonald and Bookbox, Both duenna and demurs defeated me. He was a Dormer family member and that kept colouring my view of the text. Madelina was a governess to a family in the Hague when she became involved with C.

The space in writing of Pretty est also baffled me!

Once again all is well. Brilliant.
