peachtree on Family Tree Circles

I am researching the CHRISTIE family who came to Australia per the James in 1834. They were Jane and Charles CHRISTIE and their blended family: Charles jnr, Robina, Francis, Archina, and my gg grandmother Charlotte Deacon CHRISTIE. Jane was married to Charles' brother, James Grant Christie who died in 1822. I am interested to find Jane's origins, she was born Jane Whittle born circa 1800 possibly in the Azores, Portugal. Any help would be most appreciated.
