A strange story from the 17th century. about a Lithuanian boy who lived with bears?

Maybe someone knows something more about this?

"The three Lithuanian bear-boys (1657, 1669, 1694)[21]: 21–28 [22] – Serge Aroles shows from the archives of the Queen of Poland (1664–1688) that these are false. There was only one boy who lived in the forests of Lithuania with the Eurasian brown bear; he was found in the spring of 1663 and then brought to Poland’s capital.[36]: 196 [clarification needed] The boy, named Joseph, was one of two boys seen by hunters living in the woods with the bears. He was captured at about age 9, learning to walk upright and eat cooked meat, but disliked clothes and never spoke well. The other boy was never captured; the two may have been accidentally abandoned by their families trying to avoid Tatar raids."
