A couple in China applied to use the symbol "@" as their child's given name.
Li Yuming, of the state language commission, said the couple argued that "the whole world uses '@' to write emails" and that translated it sounded like "love him" in Mandarin. [Link]

"Ampersand" has a swedish ring to it.
How about "Tilde" for German kids?..
Or more appropriate for a genealogy blog - how about "Grave" for French kids...
"Tilde" is actually a pretty good name. Short for "Matilde," I guess.
