Never heard of Ms. Fuentes, but I googled her and she rather seems to agree with me since she has dyed her hair a lighter colour! 
Ms. Duke is of course fictional, and I maintain she doesn’t look like a Daisy at all. It’s all wrong, I tells ya.
Appropos of nothing… I’ve only known one real woman named Daisy, and she was a brown-skinned, black-haired Puerto Rican.
Yes, if you consider that certain names are more popular with certain ethnic groups than others.
Growing up in a Rust Belt city whose residents were proud of their hyphenated-American identities, traditional ethnic names are still quite common. You’d be hard-pressed to find a blond Maria, Angela, Gina, or Francesca. Katherines, Kathleens, Fionas, Bridgets, and the like are more likely to have blond, red, or light brown hair. Generic Catholic names (Mary, Beth, Ann, Frances, Joanne, etc) are hit-or-miss.
Daisy Khan. From Kashmir.
I grew up in the same socioculturogeographical setting and I’ve seen what you’re talking about. Except for all the blonde Marias from Germany, Austria, Poland, Russia, etc. to balance the brunette Marias from Italy, Spain, Greece, etc.
I have noticed (or at least think I’ve noticed) this thing about young Asian girls and women having old lady names, but I totally don’t place Patricia/Tricia or Cheryl in that category. Known a decent amount of young people with that name. But if you encounter a 25 year old named Grace or Eunice, 100% chance she’s Asian.
Speaking of which, five words: The Marriage of Maria Braun.
“How do you solve a problem like Mariaaaaaa?”
Seems to be very popular in Ireland. I know three girls under 10 with the name anyway.
Do people even know how the hair color will end up at the time when a kid is born? I thought most newborns have no hair or peachfuzz.
Um, no. Grace has been amongst the top 25 most popular names for baby girls in the US every single year since 2000, so your typical under-25 Grace is an infant to 14-year-old who is probably white.
Grace has made a resurgence? Well I’ll be damned. I don’t know any 14 year olds, but when I was 14 everyone who had that name was either 100 years old or Asian. Shows what I know.
My niece- Auburn- with auburn Brunette immediate family- name is Daisy. Also. I agree Kim is dark haired unless they stereotype Kim possible. Family has Irish native american background and a long history of auburn an green/hazel eyes or dark dark brown and blue eyes (I wonder, does anyone have any information if that has a stereotype or orgin?)
Sage is in my opinion- or anyname with a soft vowel after S- is for lighter hair and eyes and olive skin
I would imagine you may be able to get an idea from the parents. Two blondes are less likely to have a brunette child (I would imagine. I know genetics are not so cut and dry).
I happened to be born with dark brown hair, given a name associated with blondes (An S name as mentioned above) and ended up turning blonde as I grew older.
