The "Margaret of Salisbury" book

One chapter completed so far and I have learned:

i) She probably married Sir Richard in 1487,
ii) They may have had, and lost, a second daughter,
iii) Edward of Warwick was probably not retarded, his only handicap being the discontinuation of his education after Bosworth,
iv) Mancini accused RICHARD of organising Margaret's (and Cecilia's) marriages to lower-born men in order to neutralise them. Clearly being a war criminal at the age of eight was not enough, he had to go on controlling people after his death.

I shall endeavour to inform Castelli and Tompsett of (i).
