I subscribe to the weekly NEHGS e-newsletter (the e-newsletter is free to everyone and I recommend it) and mentioned in this week's issue was a name equivalency site from the USGenWeb. The site offers the foreign equivalent of English names in the following languages: Czechoslovakian, French, German, Hungarian, Italian, Lithuanian, Polish, Slovakian, Russian (inc. Georgian and Ukrainian) and Yiddish (Hebrew and Jewish). I wish Scandinavian languages were included but as it is it is still a real genealogical treasure I had previously not known about.
For example, I looked up my grandmother's name. She was born in the US but her parents primarily just spoke Italian so I find it hard to believe they called her by the Anglicanized version of her name. Italian forms listed include Gia, Giovanna, Nina and Gianvannetta.
Another site I really like that has to do with names is Behind the Name because of how thorough and detailed all the names are.
I know Follow Friday is about spreading the blog love, but I'm expanding it to included favorite online resources (at least for this week).
