Mary Ann Butler was the sister of William Butler, also in the Orphan School. Both arrived with their convict mother from Ireland on the Tasmania (2) in December 1845. Their mother died in tragic circumstances in Hobart in 1855. Both Mary Ann and William moved to NSW.
Two detailed articles,
published online by the Irish journal, Carlow Past and Present, are
Warke's 'The Law Must Take its Course' and
Dianne Snowden's 'These Unfortunate Females'. Both focus on convicts Esther
Burgess and her daughter Mary; Margaret Butler; Mary Griffin; and Mary Byrne.
All but Mary Burgess brought children with them; the children were admitted to
the Orphan Schools shortly after arrival.
