parents use all sorts of thought processes to name their children. should we name boys after their father, or grandfather? so we can have juniors, or firsts, seconds or thirds? my brother was name Allan Thomas, Jr. should we pick unique names? should we pick names that have special meanings? ie my sister's middle name was Ilee, because my father lost a brother named Ivan Lee, who died at such a young age, he could only call himself Ilee. Common family names are also incorporated. I married into a whole slew full of Thomas'. Each with their own unique middle name.
When it came to naming my children, i wanted a name that would fit in at a fast food restaurant or as a lawyer or business man. So plain as the come, Robert(after a war hero uncle of my husband's family) Henry(derivative of Henrich, his paternal great grandfather, who came over on the boat). Claudia( my husband's choice, unfortunately i agreed, and found out later that it meant lame one) Rose( because it was the american name, Uncle Bob's japanese wife had) and for the last child? Sandra( I had never met a Sandra that I did not like) and Kay ( after my sister).
names are only that. parents choose them for their children. Maybe that is what pen names are for, to allow yourself to do the choosing... i don't think i really answered your question, but know this... no parent just names their children, it is thought out and carefully chosen, for the hope in it.
