I would appreciate very much hearing about this too. According to family histories on my wife's side of the family (BRAY), her father and grandfather were always known to be a little on the goofy side. We currently have two children that are diagnosed either hyperactive or attention deficit (I think this is a very serious case, not something mild at all), and I noted in the Census records for my wife's g-grandfather that he was noted as being "idiotic" at age 14 (1870 census). If there is a genetic problem or disorder, there may be some anecdotal proof of it here. There was also a very kind researcher who had some information on a Columbus BRAY from Arkansas. I have been trying to get in touch with this person but so far I have had no luck. Anyone with information I would appreciate a response.
