How about Pushkin?
Sergei Maltsov is on Wikitree. I understand (forgive my extremely limited knowledge of Russian) that his mother was previously married to Vassili Puskin, uncle of Alexander. So it seems feasible to add a profile for Alexander Pushkin and connect him. Should it be done?
(I have worked on a few profiles of Russian-born people, but orphaned most of them, I'm simply not good enough to manage them).
(And the transliterations are French, don't shoot me, I'll be more than happy to change them).
