A wonderful person, who, despite a small lack of self esteem, will one day become rich and famous.

P.S.

SHE IS NOT IRISH!!!
Mairin: Now I am rich and famous...

Me: Don't say I didn't tell you so...

Mairin is the 'normal' name for Betulinic acid. This acid has anticancer properties. It inhibits melanoma and is found in the bark of the Ber tree.

Girls named Mairin are normally pale Irish girls as the name is Irish which fits with the acids inhibition of melanoma
you can name your child Betulinic and expect everyone to awe over how awesome your babies name is
another option
just name it Mairin and have Betulinic be its nickname
