I need to find someone (Hannah Mercer from Edmonton, CA)..?

This maybe a long shot, but I'm in Canada and I met a girl in NZ and would really like to get in touch with her again. We used to be facebook friends but I deleted my account and can't get in touch with her anymore. I don't know a massive amount except that her name is Hannah Mercer, shes from Edmonton, Canada. She'll be 22 now, used to have blonde hair, is quite petite. She used to work at Neighbourhood Macs Brew Bar with me in Auckland, New Zealand and shes a lovely, really nice girl. Any thoughts or ideas would be amazing...?
