Final answer:
There is no historical evidence or reference that indicates a marriage-related action by Catiline.
Step-by-step explanation:
Catiline was a Roman senator who was involved in a conspiracy against the Roman Republic in 63-62 BCE. Although the question specifically asks about a marriage-related act of Catiline, there isn't any historical evidence or reference that indicates a marriage-related action by Catiline.
The provided sources mention the marriages of other historical figures, such as Julius Caesar and Pompey, but there is no mention of Catiline's marriage in these sources.
