in my website data for my iphone & ipad are those websites that only i have looked at? When I look at my website data I keep seeing websites showing up in there that I know for a fact I would of never pulled up or looked on.   

For example: there was one for baby names, I can't have kids and have never pulled up sites for that.   

Can it be that someone is hacking into my phone and ipad cause there's a lot of suspicious sites that aren't mine?
