In Harry Potter and the Order of the Phoenix, Harry visits his godfather, Sirius Black's, ancestral home. The walls in one of the rooms are devoted to the family tree, going back hundreds of years. Although Sirius' family is full of muggle hating, You-Know-Who supporters, with all the decent people blasted off... but I'm still envious. What genealogist wouldn't love to inherit this amount of history?
As @GravestonedPug tweeted this evening, many of us have felt the urge to cover an entire wall of our living room, office or bedroom with "Super sticky Post-its, photos, push pins, string, maps..." My dream would be to paint an entire wall with Chalkboard Paint. I'd then paint on a swirly family tree chart that I could fill in with vital stats, documents and photos. Can we say ginormous family tree? Ahhh... bliss!
