My great grandfather George William Rogerson was born around 1872 near Manchester. Early in the 1900s he moved to Dronfield, Derbyshire, where he died on 4 Jane 1949. George married a ?? Manders and they had 2 or 3 daughters. After she died, he married her sister Gertrude Emily Manders (they had to elope to the Isle of Man to marry due to consanguinity laws).
