Re: How can I measure the strength and current relevance of a name association?
I think you've answered your own question! That kind of association is always going to be personal: sadly, some people regard Adolf as a suitable name for a person they admire. Some people would think naming a child Elvis would be close to sacrilege, but others would happily give the name to a chihuahua. Fanny and Dick are probably to be avoided, but you might easily meet someone with a distinguished Fanny or Dick ancestor whom they are proud and happy to be named after.
Also, I don't know where you live, but here in South Africa we do get some American TV shows etc, but I don't watch them, so a lot of the name associations that people identify on this site mean nothing at all to me. Which doesn't bother me one bit. And when people say something like 'I could never use the name Mary because there was a horrible character with that name in a radio serial in the 1930s', I can't take them seriously. Serial killers are different, but even they get forgotten.
