Also to consider, Clary Croft, Helen Creighton's protegé. He took up after Dr. Creighton died.

Any particular music tradition? There are quite a lot of them, from the Acadians on down. Atlantic Canada comprises FOUR provinces, which means a lot of music. In Newfoundland, you have Irish. Nova Scotia has Acadian, Mi'k M'aq, German, Gaelic, English among others. Helen Creighton collected from all of these cultures.

In PEI, you have Acadian and Scottish (Gaelic as well). Probably others too.
In New Brunswick, you would have all of the same as Nova Scotia.

Oh, also there is the Black culture as well as the United Empire Loyalists.

In Halifax, we still have Shape Note singers descended from the New England states.
