Mrs Smith is recognised as an important scholar. One of her books is considered a classic, she developed two theories, received several awards and there is a Wikipedia article about her in three languages.
Mrs Smith received the Jessie Bernard Award in 1993 and it is why I learned about her. The Wikipedia article mentions two brothers, one is linked the other is not. She was born in Northallerton, There is a link to John Porter but the only relation to Mr Porter is that Mrs Smith won the John Porter Award. The award was given for a book by a red-linked organisation an organisation that bestowed their 'outstanding contribution award' to her as well in 1990.
This outstanding contribution award was given in 2015 to a Monica Boyd. She can be found on the Internet as well, it is easy enough to expand the amount of information around a relevant person like Mrs Smith. Almost every line in her article contains facts that could be mapped in Wikidata. With some effort sources can be added. The only problem is that adding sources for everything is painful; it is just too much work. This is a reality for Wikipedia as well, When Wikipedia and Wikidata align, when its links / statements match, it must be obvious that the likelihood of facts being correct is high, if only because multiple people had a look at most of the facts.
