The problem with Ada Lovelace and Rosalind franklin is thatthey are rightly overshadowed by others.
Conraray to teh mythology Rosalind Franklinw as not screwed over her experimental work was as was Wilkes but here preferred model of DNA was wrong and Crick and Watson had the insight she did not have. She was a significant scientist but it doesn't make sense to honour rather than those who actually did discover the structur eof DNA rather than help in doing so.
Ada Lovelace's contribution is massively overblow and exageratted clearly Bababge had to have had all the ideas about programming and have example programs he wa susing a stest cases and input to the design of the thing itself. Again she may well have been impressive but why honour her when her part is necessarily far less than Babbage's.
Now Noether. She is a worthy recipient but probably not considered as not British.
My favourite, head and shoulders above other in my opinion, is James Clerk Maxwell.
