Does it whither...?

This weekend I watched Stephen Poliakoff's Perfect Strangers for the second time. It's a brilliant little telemovie starring Matthew MacFayden (that's Mr. Darcy in the movie adaptation of Pride and Prejudice, for you Americans) about a family of strangers gathering in a posh hotel to piece together their family tree. On thinking of the movie afterwards, however, I began to fixate on what our family tree might look like, and more personally, what future generations might think or say on seeing a branch end at my name. Would they wonder why? Wonder that I was emotionally unable? Impotent? Homosexual? Would it be an anomaly? I know I've at least two cousins potentially in the same position...

If I ever were to marry in the UK, would my staunchly middle America family dare to encrypt 'Brian Paul m. [man's name here]' into the geneaology? Or would it remain a graphical white space excising a story one would rather wasn't told? Poliakoff's point that the real connections and fissures in a family have no relation to a family tree is real enough, but who will live to tell the stories of my life...
