One of the reasons for the realtively little work done on the Hey family/s of Yorkshire it the sheer weight of numbers, in the Bradford Yorkshire telephone book alone there are something like 3 or 4 pages or more with each page have three lists of Hey names. The family seems to be heavily weighted to boys, My father is one of 4 boys and in my generation there are only 3 girls, My father has three sons and a daugher(me) of his 3 brothers two had one son each, his other brother had at least two sons and two daughters. His father I think is one of seven, His father was from Keighley. One of the Universitys in England wasdoing a genetic survey of Hey's in 2002, University of Leicester I believe. There must of course be some overlap as familiesdon't actually get larger the further bag we go just more interconnected.
