Hi mollipops. The Argus of 01 Sept 1852 prints Nicholas COOGAN is searching for sister Catherine, arrived Liverpool 4 years ago.
The Argus 10 Aug 1849 prints the New Liverpool has arrived with 211 female orphans. A lookup provides Catherine's age as 17.
Yes that's the same Swiss David arriving here ship wrecked at Barwon Heads, Earl of Charlemont 18 June 1853.
