Not only can you get a good idea of age from a name you can generate names that match age and sex. I have a niece who recently did a science fair project where she used Markov chains seeded with U.S. census data over the last hundred years to create new names. With about 90% accuracy people could tell if a fake name was from 100, 50, or <10 years ago and the sex.

An interesting side note was that she put in a simple profanity filter but in all of her trial runs it never picked up any "fuq" or variant names.

Edit: Here are sample boy names: Shill Flay Roshard Per Coll Milius Madfrego Derry Fer Fordy Carlel Marler Rommyronance Jord Felwooke Rott Luper Bent Zekin Othen Nolanterry Jerarton
