In view of Bruce's continued popularity and his apparent interest and pride in his Italian/Irish/Dutch roots, I was surprised to find that his Geni family tree was a little sparse. I have therefore spent a bit of time recently trying to fill it out, including citations to source documents where possible. There are still some branches left to explore, however! Not surprisingly, it has been difficult to find good documentation for his ancestors before their arrival in America, although it seems that genealogists have put some effort into this. I would be interested in collaborating with anyone else who has an interest.
