1896 Oct 1. Born Northumberland. There are two Robert Skelton that satisfy the birth criteria, both born Oct/Dec 1896 in Northumberland. And Ancestry tree gives that son of James & Elizabeth Skelton died in France in 1918. So our man must be the other Robert, whom we can get from the census. The choice is actually what you would have expected from the two men's level of family wealth.
