I quite like it, but there are other feminised male names that I like better. I don't find it particularly dated.
Thinking of feminised names, my problem might be simply that when I like a male name, I'm less likely to like its female equivalent. I like
Stephen a lot, for instance. But I don't enjoy
Anthony,
Cecil,
George,
Harry or
Philip nearly as much as
Antonia,
Cecily,
Georgina,
Harriet or
Philippa.
