Well it is too long since I studied her tale for A-Level .... but while I remember one husband was Jannekyn I am fairly sure none of the others were called bath. Teh womann of Bath was she and not a lowly one either ( do any other Archers fans think Lilian Bellamy?) . As for the number of husbands she had - well I cannot resist saying that it rather depends if you mean just her own ...
Of course in German Mann means husband as well as man. I remember when I visited German friends, Frau had travelled separately since she had to collect someone else and when she arrived at the venue... she wanted to look inside to see that Herr, and I and her Aunt Lise-Lotte had arrived already arrived without giving up her ticket explaining to ticket collector "Ich besuche mein Mann" (I am looking for my husband" However he heard it as "Ich besuche ein Mann" (I'm looking for a man) and answered (and this goes too far beyond my skill ) "There are lots of men in there - take your pick!"
