#Wikipedia - The death of Lanier Meaders

Mr Meaders was a notable potter who died in February 1998 according to folkpottery.com. The English Wikipedia article however is in two minds about his death. Yes he is dead but when did he die?

According to the category he was one of the living death for 10 years. In the text the year of his demise is correctly stated as 1998. By googling for a source another date was found.

As I am not an English Wikipedian, I do not know how to indicate sources in English Wikipedia. The date of death in Wikidata does have a reference. The question is how differences like the dates of death of Mr Meaders are found and improve the consistency in the information that we provide in all of our projects.
Thanks,
