So my search for the real father of my wife's Aunty Mary must now take on the guise of a scientific expedition. I need to exhume the grave of the dear departed lady, get hold of some of her DNA and determine whether or not it contains any of the typical Berry DNA markers. As far as I can make out from the Berry DNA Blog (indeed, such a thing exists) I need to look for "haplogroup K with CRS differences in HVR1 at 093C, 224C, 249C, 311C and 519C and in HVR2 at 73G, 195C, 263G, 309.1C, 315.1C, 497T, 524.1C and 524.2A". Questioning my wife about where her late Aunty Mary was buried or whether - by any strange chance - she might still have one of her old hair brushes has resulted in nothing but odd looks and those whispered telephone conversations with her cousin Carrie which normally involve the phrase "he's gone funny again".
I know she died about 25 years ago and the home she had been confined to for most of her life was somewhere near Chesterfield. I assume that there must be records of where they buried the residents - all that is needed is good, old-fashioned research ..... and a decent spade ..... and a dark moonless night.
