Adele

My great-grandmother was named Adele. She passed away at 95. I really hoped she would make it to a hundred: she had lived through both wars poor thing, she deserved a 100. Anyway, I was saying that Adele was the name of my great-grandmother, and honestly, I've never heard of anyone else by that name. Who the hell is this Adele here (who judging by the photo is still quite far from my dear great-grandma's 95 years)?
