Maria Mary Hedican Hedigan

Have been researching Maria who was born in 1847 in County Clare; father Martin and Mother Mary/Margaret nee McNamara.

On Ancestry a small screen pops up saying she was born in 1837 not 1847. She married John Phillip Harper in Ballarat, Victoria, Australia in 1869.

Have been advised she went to Australia when she was 12 or 13 but have checked shipping records and cannot find the Hedican/Hedigan family anywhere.

Any help will be very much appreciated.
