There's a Hugh Perry, widower, who marries Elizabeth Hutchens on 5 Feb 1771 in Deptford, Kent.
That's way down south, near London, and far from Sunderland, even by today's standards (thinking England, not mighty Canada). But Deptford is on the Thames, and Sunderland on the sea, so there might just be a maritime connection.
Source is from Family Search, also indexed by Kent Family History Society in their West Kent Marriage Index. St Paul, Deptford marriages 1730-1812.
Hope that might help if you've not already spotted it.
(I once spent a lovely summer in Winnipeg many moons ago, but wouldn't cope with the cold at this time of year)
