Here’s an idea for you. Perhaps we should all be all allocated a number at birth and as soon as we are old enough, chose our own nameTalking of names, my granddaughter had three changes of surname before she was even 18-months old.
My son's partner registered the birth using just her own surname so, Hollie May HERsurname. When my son complained it was changed by deed poll to Hollie May HERsurname-SONsurname. The couple had already separated, soon she remarried and took his name so now it became Hollie May SONsurname-NEWsurname.
