Count Olaf is said to be a distant relative of the Baudelaires (their third cousin four times removed or their fourth cousin three times removed, though it is not revealed as to whether he is related through Bertrand or Beatrice). It is also possible this relation is a lie he fabricated so that he could adopt the Baudelaire orphans.
- This family tree is based on conjuction through what is known in the series, and assumes that Beatrice took Bertrand's last name.
- They were named after the poet Charles Baudelaire whose most famous work is The Flowers of Evil, a cycle of poems that discusses dreadful circumstances and finds beauty in them.
- The Baudelaires are Jewish.
