Of course names still have personal meanings to us but in the broader sense of culture, how we name ourselves and how we let our names be used has a huge impact on how we structure ourselves as a society and in turn our collective identity. Names like identity have to change over time, the baby name your parents used may not be appropriate for your grown up self. You may have had a nickname in your teenage years that stuck.
When I was in school, years ago, teachers would make up Irish names for those of us with English surnames or first names. My maiden name of Eustace- got changed regularly into Eustach (pronounced ewestash!) this was completely made up. similarly many Irish names and words have been made into English by a process of welding English words onto Irish words or taking an Irish word and finding an English word that sounds similar and simply changing it.
Ireland is a made up Irish into English word-what does that say about our identity?......... not a judgement, just a question, a place to look from or at for awhile, would we want to change our name, if we did, would we go back to Eire, which is still used at times, or what if we could choose our own name---could we do it as a country?
