My family are all from Dundee in Scotland and have been for a long time.
Parents are Graham David Ogg and Elizabeth Ada Ogg (maiden name Gage).Grandmother was Jean Ogg.Not sure of Grandfather's first name but I can find out if anyone needs to know.
As far as I know, they lived in Dundee all of their lives.
According to the Dundee Telephone Directory, there are many Ogg's living in Dundee who are not know to be in my immediate family, I was even in the same year at Dundee University as another Stephen Ogg!! Although not studying the same subject, that would have been too weird!
