Okay...usually I don't do this but I know for a fact that fanfiction has so many readers that at least one will help me find this story...
I read this a few years back, not even sure if its still on the site anymore its been that long but I'm still gonna try and find out if it is or not.
The story is a Naruto fanfiction about how the fourth hokage, named Arashi Kazama in it, either comes back to life due to some jutsu and is found by Naruto and somehow after receiving a mission together they head for this village that is hidden and since Arashi knew the Clan leader it made it easier to get in. Naruto doesn't know that the fourth is his father and is...well not exactly keen on his presence but gets won over after the older blond takes a kunai to the back for him. Now this story I know ended. It had Arashi and Kakashi fighting in the last chapter, proving to Kakashi that Arashi is who he says he is.
In the sequel of this story the fact that Arashi's wife is dead is finally hitting in and he's become depressed. I'm not too sure on the details but Naruto ends up living in the Kazama mansion where he finds out about Arashi son by finding the nursery. Eventually they somehow end up in a village, helped by someone who knew Arashi's wife and also found by his wife's brother; who hates Arashi for her death. I don't remember his wife's name but I know she had long black hair and blue eyes in this story.
Okay...I think that's it. Please try and help. If you know the story please review the answer. If its no longer on Fanfiction and you know another place where I can read it, go ahead and review for that too.
Thanks!
