Thanks - I have got it now. I found the 4 down clues to be altered, but kept on looking for names and saw that 4 answers could be altered to Amos, Ewart, Stella and Vera. These were red herrings.
The across person wrote The Rose and I thought this was relevant, having 1A, but I eventually realised what this was altered to, and the synonyms.
Brilliant puzzle with so much to it.
Thanks Ranunculous.
