In researching ancestry over the last few years and reading the information found out by other family members, I've noticed several male ancestors or those known in my childhood (great uncles for example) who used their middle name as their first name. There are three recent male Prime Ministers similarly (James Callaghan, Gordon Brown and Boris Johnson).
Yet I have not come across any women in my family/ancestry, nor indeed any women in public life apart from actresses. So is the use of middle names just a family quirk, or is this more widespread that only some men use middle names?
