I remember my own great uncles and aunts (on the Allen side) assembling en masse for Great Aunt Margaret's 80th birthday.(Or was it her 70th? Who knows?) They were very dignified and ancient- and intent on playing a serious game of bowls they didn't want a small boy getting anywhere near.
Also, they were all dressed in Edwardian clothes- boaters, blazers, ankle-length dresses with cameo brooches at the neck- but they can't have been, can they?
