How Sir Launcelot was espied in the Queen's Chamber, and how Sir Agravaine and Sir Mordred came with twelve knights to slay him

Also done in 1857 and it looks like Jane to me. Lancie looks different again BUT if Rossetti had fallen in love with Jane (and we've all been there) the legend 'How Sir Launcelot was espied in the Queen's Chamber, and how Sir Agravaine and Sir Mordred came with twelve knights to slay him' sounds like jealously to me. 

I must point out that several studies of Guin. in 1857 used Val Prinsep's wife but to me she looks quite different.
