I love
Mary,
Mary names, and most names that start with
Mari or Mar.
Marigold wouldn't be my favourite of such names but I do like it. It sounds fresh and interesting. I do agree that it would probably be better as a mn, but workable as a fn.
Helena Marigold - I like this. I don't know the song so I wouldn't make the connection. Good combo.
Colette Antonia Marigold - Not a fan of
Colette but the name has a nice flow. I like
Antonia Marigold better.
