Got through this without too much head scratching but have one ??? for 39a 'Byron's daughter is ....' The answer is clear from the first part of the clue but I've tried juggling the option for the 'husband's away' part of the clue to no avail.
Thanks Malone, I hadn't realised it had been raised before. I've tried jumbling with 'h' and 'hub' and 'man' etc and looked through the appendix of Chambers at women's names etc. Hopefully someone out there can enlighten us!
