Lennox has flit on and off of my long list within the last year. I first heard it on a girl on the show 'Melissa and Joey' where a main, female, teenage character wore it (and wore it well, imo). I definitely think hearing it in real life would boost it too!
I'd name Lennox's sister, Peyton. Not sure about a brother, maybe Kaden or Jack.
