I was browsing around on the Internet and found this article which says that giving a boy an unusual name is a bad thing. I also found this blog in which a grandfather-to-be also suggests not naming a boy something unusual.
I'm not sure of the age of either of the persons who wrote the above, but I have a feeling that they're most likely Boomers (and if not then not more than a few years on either side from being one). Remember the last couple of my blog posts which mentioned how Boomers appear the biggest supporters of gender double-standards? The same thing applies here; if someone suggests using an unusual name for a girl but steering away from one for a boy chances are he/she is a Boomer (or possibly early Xer).
ETA: Although traditionally boys have overall been given more conventional and less creative names, it seems that Boomers and those around the same area in terms of cohort have been more blatantly divergent on how boys and girls are named then previously (e.g. how G.I.s named their children).
