Why has Heidi made a massive comeback? It's all over MN all the time, does it appeal to younger women than me - I'm in my mid 40s? I agree it seems very 70s like Kelli, Shelly, Lori, Jaime etc. All my Californian DHs cousins have these names. What was the cultural trigger that put Heidi back on the map? Is it Heidi Klume? It's short for Adelheid. If you like German what about Heike (Hi-ka)?
