Hi Ky-Lee,
I have been tracing my Hall family tree and noticed this post by you. If my research is correct you are researching the Corrigan family who are connected to the same Hall's. It was interesting you posted about Booby Island because Elizabeth Hall (my GG-grandmother) married Horatio Smith who was the 1st Lighthouse Keeper on Booby Island when it began operation in 1890. Alice Hall, who married Robert Corrigan was a niece of Elizabeth Smith (nee Hall).
regards,
Anthony
