History buffs might find it interesting that as of today, one of Vladimir Lenin's distant lines managed to get merged and connected into the World Family Tree (through a merge on Catarina Sofia Planting-Gyllenbåga). So, it's at least theoretically possible to catch a path for the Pro's. And yes, granted, the path is not a bloodline, but it might still be interesting since the nodes in question are fairly well researched and documented in various quality sources. Geographically the path runs from Russia, back in time and into Sweden, making the Big Tree connection around mid 1600s, possibly with some interesting stories in-between. Anyway, this currently only path 'out' looks like this:
Vladimir Ilyich Lenin
[his mother] Maria Alexandrovna Ulyanova
[her mother] Katharina Eleonora Ivanovna Essen
[her mother] Anna Beata Östedt
[her mother] Anna Christina Borg
[her mother] Anna Brita Novelia
[her father] Simon Novelius, Sr.
[his brother] Johan Novelius
[his wife] Catarina Sofia Planting-Gyllenbåga
[her husband] Michael Planting-Bergloo
From the final two nodes, it should not be too difficult to pick up a path.
