Who were her parents?
She was born on Prince Edward Island, where she married James McQuade in 1849. Her husband was born in Ireland about 1818 and was recruited by Father MacDonald in Glasgow to work the MacDonald feudal estate on PEI. McQuade operated the inn and shipyard at Mount Stewart, PEI.
Did she and her husband inherit the shipyard from her father, who was of an appropriate age to have been one of the shipwrights hired to maintain the grand banks fishing fleet feeding the British army through the Napoleonic wars, as forests on the MacDonald estate were being cleared for conversion to agriculture? (possibly providing a source of lumber for shipbuilding)
