Hannah was named after her paternal grandmother, Hannah Prangle. She was born in 1861 in York, Western Australia to John Wansbrough and Ruth Taylor. Hannah’s father died in an accident before she was 4 years old and her youngest brother just a few months old.
Tragedy struck again for the family in 1874 when Hannah’s step-father and next youngest brother drowned in a boating accident on Monger’s Lake. This must have been a blow for Hannah as there were only 14 months separating the siblings and they would have been close.
