About William Sidney, MP
There is much uncertainty about the origins of the Sidney/Sydney family, and particularly in regard to this William (d. 1449) and his son William (d. 1477), both of whom were MPs. in the biography of the younger William in Wedgwood's History of Parliament 1439-1509 (pp. 768-9), it says "whether his mother or wife were Cecily, Isabel, or Thomasine - a Mitchell or a St. John or a Barrington - and who was really the ancestor of the House of Penshurst remains in 15th century obscurity". A footnote to this account cites three conflicting pedigrees of the family.
Part of the problem is that during the Tudor era the family commissioned Robert Cooke, Clarenceux King of Arms, to construct a pedigree for them. According to a long note in CP 7:553, the resulting pedigree is clearly a forgery - although when it starts being accurate (if at all) is unclear. You can see a printed edition of the forged pedigree in the original series of Misc. Genealogica et Heraldica, 2:161ff, available for download here:
As to the daughter who married John Michelgrove, I've seen her variously named Anne or Mary, and also variously assigned as a daughter of either the elder or the younger William. I think a chronological case can probably be made for either William as her father. BTW the sidney daughter who married an Appsley appears to be a separate individual from the one who married Michelgrove.
