Hi Hannolans, I've just picked up an old error of yours, in Susan Close (Q7647681), the South Australian politician - you added Canadian citizenship as you have confused her with a Canadian academic, photographer and write with the same first and last names - see https://www.susanclose.com/about. These are two different people. I've removed the false info from Susan Close (Q7647681), but as I'm unfamiliar with Wikidata I'll leave you to chase up the other person's entry, if it exists.
Cheers, Bahudhara
