I'm an Elizabeth Gail and as a child apparently called by that full name....at some point, I started referring to myself as just Gail and it stuck with my parents. In high school, I had a male friend who enjoyed annoying me by calling me Lizzy Gail - I must say at some risk to his general health :-)
It would amuse him to no end to find that now at age 64, I've started a handmade purse business and am calling it Lizzy Gail Bags!!
