I am researching a Julia Appleby who was an orphan sent to Australia with a boat load of female orphans to be domestic servants. Julia left Cork in Ireland in 1850/51. Sh worked in Hobart Tasmania for a Reverent Lilly, later married an Edmund Ryan who was a convict from Tipperrary.
She was my grt grt grandmother. Later she left her drunken husband and moved to the mainland of Australai but no further records are available.Could she be elated to your Thomas from Cork.
