On the passenger list of the barque "OLYMPUS" arriving Wellington 20-4-1841 from London, the entry under the MABEY family says that "Sophia 10 years left behind W.A."
PASSENGER LIST for OLYMPUS

Does anyone know what that means ?

I cannot find the OLYMPUS arriving in W.A.
(what I ASSUME to be West Australia) in 1841 to drop her off.

*UPDATE* - Apparently Sophie died during the voyage and was buried at sea 'off the coast of West Africa'
