Deletion of Princess Marie Gabriele of Luxembourg

Comment: to Jean, Grand Duke of Luxembourg, with a soft ability to re-create. She's a collateral relative of a reigning sovereign, but remotely in the chain of succession. I say not to delete, because, due to her philanthropic activities, material in theory could be found to re-create the article. A redirect is also |commonly done for cadet branches and lesser nobility, to redirect an article about a princess or duchess to the reigning parent
