I love Jack, agree with pp that Brady is too trendy, especially with the classic sibset you have so far. I agree with pp suggestion of Benjamin and would add Thomas, Andrew and Theodore as suggestions.
Have you checked out the recently released 2013 baby names? It seems like you trend toward the popular names. What about Liam? It's NMS, but I think it goes with your name theme. Of the names you suggested, Henry is by far the best....even though it is becoming more popular now it'll still always be classic and timeless. Husdon is awful, makes me think of the dirty river over yonder.
