Dear Dave,
WOW, Im absolutely gobsmacked. THANK YOU so very very much for your help. I am in the process of trying to obtain the shipping records for the Northumberland to see whether Honora came to Australia with other members of her family. There are records in launceston Tasmania pertaining to a Martin, Bridget and Cornellius Darcy. Unclear at this stage whether they are related to her or not.

Do you know if its possible to obtain death certificates? And if so, would these have additional information regarding John Darcy and Mary Gleeson's parentage?

I am so very grateful for your information and advice. What a lovely way to begin my new year. THANK YOU. Im off to the IFHS to obtain the baptismal records.
Kindest regards
Kate
