Several web-sites relate the unreferenced story of Major Summerford:
A British officer, Major Summerford, while fighting in the fields of Flanders in February 1918 was knocked off his horse by a flash of lightning and paralyzed from the waist down.
Summerford retired and moved to Vancouver. One day in 1924, as he fished alongside a river, lightning hit the tree he was sitting under and paralyzed his right side.
Two years later Summerford was sufficiently recovered that he was able to take walks in a local park.
He was walking there one summer day in 1930 when a lightning bolt smashed into him, permanently paralyzing him. He died two years later. But lightning sought him out one last time.
Four years later, during a storm, lightning struck a cemetery and destroyed a tombstone.
Sullivan was a park ranger, so he upped his odds by being outdoors a lot. The same went for a sportsman named Major Walter Summerford, struck three times, whose gravestone took a shot four years after his death.
Are there any well-referenced versions of this story? Is it an urban myth?
