Would you like me as a native German speaker quote standard genealogical and academic German literature more extensively? Where would you draw the line, a statement that non-English speakers are not welcome? Frankly, one of the more annoying aspects of working with WikiTree is this absolutely Anglocentric way of approaching everything else in the world, from laying claim to English being the one legitimate language by some to name people to name orders that transliterate names as Zedong Mao just because I suppose we in the West have an exclusive right to decide how things and people should be named.
English as a lingua franca for the website has an absolute place, but I for one would welcome having the names, locations, and bios of Russians in Russian and Cyrillic, with the English transliteration in the Other Name field and an English synopsis of the bio appended to it.
