Well not quite famous, but Sir John Franklin who has been featured in some history specials and books, plus he's who Sinead O'Conner sings about in "Lord Franklin" ..and his sister married Alfred Tennyson, so I'm connected to him by marriage.
Oh and one of the Dukes of Gainsboro, but again, not quite famous (and I don't even remember his name.)
That's all I got.
