Cap Watch commenter Brian Carroll raises a good point: How could Nancy Wyman be the state's 108th lieutenant governor and Dan Malloy only the 88th governor?
The discrepancy can be partly explained by the fact that many lieutenant governors served brief terms (from William S. Holabird in 1842 to Benjamin Douglas in 1861, one- and two-year terms were the norm, as they were 1893 to 1913.)
As pointed out by Carroll, Connecticut had a Deputy Governor before 1818.
And it's also important to note that the lists of Connecticut's governors and lieutenant governors include colonial governors.
