I'm not familiar with Margaret Oakley Dayhoff, but I am aware that Rosalind Franklin [1] was extremely important for our understanding of DNA, comparable to Watson/Crick, with whom she co-discovered the structure of DNA. So it seems "Rosalind" is at least very appropriate as a name for a genomics tool such as this.
Not to say the other names mentioned aren't also deserving of similar honors
