Sarah_Jane on Family Tree Circles

My g.grandmother is Elizabeth Cecilia Meehan born Feb 29 1898 in Brisbane Queensland Australia arrived in Vancouver, B.C. may 1 1912 on the marama, married Martin Bartoo in 1914 in San Francisco California. Above are facts with proof, I was told she was orphaned at birth, was raised by a barron aunt who planned for her to go to san francisco to be come a nun. When they arrived canidated were not being accepted for a few months. I would like to know if this is true and who her parents are so I can go further in Meehan line.
Thanks for you help in advance
