When I give a name to my bank or council tax or utility provider, and they then leak a different name, i can use the Information Commissioner to enforce correct data usage and to provide sanctions. (In theory. IRL they are too busy and too soft).
Right - but at some point she gave them the other name, whether she claims she didn't, or "doesn't remember". Google didn't pull her name out of a hat, and it's not magically associating it via advertising / cross site correlation otherwise.
