Q. Who was Jesus’ biological father? How did His mother Mary die? When? Where?
Christians believe that Jesus had no biological father. Rather, his mother Mary conceived him while she was still a virgin. This was a miracle, and so it is unclear how it actually happened. Even the angel who spoke to Mary about it described it in a figurative poetic parallel: “The Holy Spirit will come on you, and the power of the Most High will overshadow you.” So this is a mystery of the faith that Christians believe and accept by faith.
As for the later life of Mary, the mother of Jesus, please see this post.
