My father and his parents immigrated to the US in 1908 from Lens, France. His parents were Leon Duffroy and Nellie Camus Duffroy. I wonder if there are any relatives there still? Leon's father was Floreal Duffroy and his mother Marie Duffroy. They should be buried in Lens, I think. I saw photos of their gravestones when I was a child, but evidently they have been lost.

Any help will be appreciated.
