Talk:Alexander Ulyanov

I was working for the dutch wikipedia and found confusing information. This site says that Alexander died the 5th of may. But the Marxist Internet Archive says it hapened on the 8 th of May [(http://www.marxists.org/archive/lenin/works/lifework/worklife/1890.htm]. To make things worse an other source advances the 20th of May . This last one may be due to the difference between Julian calendar and the gregorian calendar, though this would imply that Alexander died on the 7th of May(Julian calendar). Can someone check other sources?
