[Facts] Re: Two questions on Russian names
Lara is the nn for Larisa, and is close to Laura.
I've never seen Chapeka before. My first thought was Karel Capek, the Czech writer. The only Chap- word in my Oxford Russian English dictionary is chapyga, which means plough-handle, stork is aist, and -ka is the diminutive suffix for anything. The site says that it is from a Czech name, so you might want to look into that language.
