Not a huge fan of those. Rubi-Rose is probably the best of the three but I don't like the spelling or that, as was mentioned below, it's a lipstick shade.
Payton and Porscha are just nms.
If I had triplets and I was going for hyphens I would just lean all the way in and make them all Marys, let's be real, this kind of an opportunity shouldn't be missed (
Mary-Ann,
Mary-Beth, and
Mary-Jane) but realistically I know I'd probably encounter opposition so sensibly I'd settle for:
Betty-May
Emmie-Lou
Mollie-Ann
