My great-great grandmothers maiden name was Dellacosta. Her first name was Catherine and nothing else is known about her. I don't no where she only that she moved to New Zealand, and I don't even know when that was. My grandmother believes she may of been Italian but isn't certain. I know it's not a lot to go on but can anyone tell me where the name comes from or what it means.

The name is more commonly written Della Costa and it means 'from La Costa', a placename in Italy.
