Before anyone flag this post as duplicate of why-gods-name-to-people let me clarify that this question is specific to name Shantanu and I am not asking why people name their kids with Hindu God's names hence I think it is not duplicate.
As many of us already know, it is very common that Many of Hindu people have their names starting from Hindu God's names.
And the reason to follow this practice is : the sin destroying effects the Lord's names.
But to the best of my knowledge, and most will agree with me, that the most famous Hindu character with the name Shantanu is in the epic Mahabharata, where Shantanu is best known for being the father of Bhishma (and not God or any incarnation of god).
His own identity is not that special when compared to his successors like his Son Bhishma or Arjuna later in his family.
Wikipedia does mention some good qualities of him, but that does not substantiate him to god-like status.
Also, Meaning of name Shantanu is: Whole (Does not sounds god-like name)
Now Still I found many people with name Shantanu in Hindu community and that also includes few famous personalities too.
What is so special Shantanu did(either in Mahabharata or any other incidence) which influenced Hindu community in general, to use his name for naming their own kids?
Or is there any other character with Name Shantanu who was god-like figure?
