Hi Mary, hope you had a good Christmas and New Year. I haven't read the work by Elwin that you refer to, but my library does have a copy of 'Lord Byron's Wife' by the same author which I shall read. Apparently it caused such a controversy when it was first published, that the Times Literary Supplement had to write an editorial stating that they would not be publishing any more letters relating to it. The controversy rages to this day, with the Annabella camp claiming one thing and the Byron camp claiming another, as we have seen on this site.
I don't believe any marriage, including Charles and Diana, has had more books and articles written about it than Byron's marriage to Annabella. What's even more amazing is that they were only married for about a year.
If I could recommend 'The Kindness Of Sisters' by David Crane; it's useful for it's pyscholigical (have I spelled that correctly?) insight into Annabella - not the world's most pleasant woman.
Keep in touch...bye for now...
