Hi Barbara, I have quite a few books on old Macclesfield, and in one there is a picture possibly of Brenda Goodwin. The first silk queen was Lilian Jervis in 1930 who worked for a local silk producing firm. The idea was to promote silk across the country, similar apparently to cotton queens in lancashire. The silk queen also appeared in the local carnival. The tradition died out and was briefly resurrected in the 1970's. The local Silk museum should be able to give you much more info than I can, I realise I am responding a bit late and you may already have plenty of information.
regards
Anne
