As a first step in your quest for assistance I would direct you to the excellent thread by John(from Arran) concerning postings on this site.
I am sure you will get all the help you need if you adhere to this.
OK I remember now. Although not given in the crossword (and I may well be wrong), I think the theme is "Events in January" and this one is BURNS. Others that I also remember are UP-HELLY-AA, CHURCHILL (died in January) & ST AGNES EVE (20th January).
