5th grade social studies question

[RedTailHawk]

DC brought home a graded social studies sheet where the students were asked to list unique characteristics for each of 3 colonial regions (New England, Middle & Southern).

DC listed "Mostly Catholics" as a characteristic of Southern. The teacher marked this as correct and DC says this is what they learned. There was very little in DC's notes or folders from social studies class and nothing mentioning Catholics.

I am familiar with Catholics settling Maryland and St Mary's City but I thought Catholics were still a minority in the 13 original colonies. If one of the 3 regions was to be described as "Mostly Catholics", I would think it would be the Middle and not the Southern.

Am I missing something or is this a teacher oversight/student error?

TIA

Maryland was the only Catholic colony:
