This Family Tree of Hearts is customizable from PersonalCreations.com. Though you have no control over the arrangement of the hearts on the tree or which heart the names appear on, this would make a lovely addition to any home. Click on the image above to get the details.
If you have the time and desire you can paint your own version. Theirs is on canvas so you could pick up a pre-stretched canvas and get to work. Or you could use wooden planks to replicate the look of the background. Doing it your self you could put the hearts in a more traditional family tree arrangement, though I can see some advantages of the random approach. Doing it yourself would make it possible to add more hearts as new members join the family.
