Yes, the Roman calendar called the month "Aprilis". 10/12 of the modern Gregorian names were present in the calendar used by the Roman Republic (~500 BCE). Mark Antony renamed the month of "Quintilis" to "Julius" after Julius Caeser's assassination. The senate renamed "Sextilis" to "Augustus" in 8 BCE to honor Julius's grand-nephew who ruled for 45 years as the first emperor of Rome.

Of course, the Romans didn't use 'BCE' at that time. They referred to years by the consuls who held office that year.
