I have the Hovenden name in my family tree. Emma Amelia was my great grandfather's sister. She married Robert Thomas Hovenden in 1892. Robert was the son of Robert Thomas Hovenden and Ann Malone and was born in Kyneton Victoria. His father (Robert Snr) came to the colony with his parents Henry Hovenden and Catherine (nee Noonan) on the ship Navarino, and his brothers Thomas, John, William, Henry and Richard. Is this Catherine possibly your Catherine? This is the only information I have on the Hovenden name. Regards Ellen Ryan
