Do your research buddy.
It is not likely it was called 2nd Lieutenant back then. The earliest mention of the rank 2nd Lieutenant was an entire century after your officer had commissioned. The British Army had not switched to the 2nd Lieutenant rank until 1877 but it is believed the Royal Marines had used it earlier than that. Also, the sub-altern ranks were not as official as they are today. Your officer may have been a 2nd Lieutenant in the same sense of the word but he likely was not called a 2nd Lieutenant. sub-lieutenants were still considered lieutenant. This is also why he is mentioned as being promoted to Captain-Lieutenant. Which is more traditionally what we would think of as being a First Lieutenant in todays Marines

Rude.
Reference in page 237 of Volume II of
Historical Record of the Royal Marine Forces by Paul Harris Nicolas(1790-1860) blatantly states that a the first royal marine battalion consisted 8 companies led by "2 majors, 9 captains, 14 first and 4 second-lieutenants". Your post above states that: "The British Army had not switched to the 2nd Lieutenant rank until 1877 but it is believed the Royal Marines had used it earlier than that." This isn't true because the royal artillery, engineers, and 95th rifles had established the rank of 2nd lieutenant well before 1877. Thus, during the napoleonic wars, 2nd Lieutenant was a real rank that was being used in both London Gazette "terminology" and regular marine forces as well. Also the rank of captain-lieutenant was separate from that of a 1st Lieutenant, and was actually abolished in the early 19th century, often given to the senior lieutenant in a company with no captain.
