Quoting Jaide Spencer:" I highly doubt that they will judge her by the way its spelled but probably more on her background, education, ... [snip!] ... i like them all but jillian, it seems like the name off an old woman to me and people may quickly start calling her jill.."
Of course they will - I majored in HR, it is extremely common for names that have weird spellings to be just thrown out because they aren't clear on the pronunciation, they looks silly/ down market / uneducated. There are 500 other people with the same qualifications, why would they want someone whose name looks like they are the product of an uneducated teen mom. (No offense - but the large portions of teen moms I see have awful taste, no all, but I would say the majority).
You want your daughters name to be "catchy"? lmao - wtf? No - you're "child" is only a child for a very short time, they spend the majority of their life as an adult and to give them a name that's "cute" is unfair and selfish. Your child deserves a name that will grow with them and won't hinder them in a professional setting.
OP: Jillian is a beautiful choice - classy, uncommon (how many baby Jillians do you know?) and most importantly - it fit's a person at every stage of their life.
Kaelyn is a hot mess, sorry.
