Kate Prideaux

My g grandmother was Kate Prideaux. She married William Henry Cook 1891 in Sydney. They lived in Wellington NZ - when they went there I don't know. According to my grandmother's birth cert, Kate was born in Wellington NZ. I have a copy of the Cook/Prideaux wedding cert on order, but any connections would be helpful. My grandmother was estranged from her family in 1924 and I have no information on them other than what is stated here.

Linda
