I did give my opinion to my son on some of his suggestions to name his baby. He asked and I gave my opinion honestly. He was actually considering “Ulysses” or “Aurelius”! I reminded him of how cruel kids can be in school and tease other kids with unusual names. U. S. Grant was called “useless” as a play on his name and went by “Sam”.
In the end, they didn’t choose Ulysses or Aurelius. I don’t like the name they chose but it’s not as bad as those.
I know both male and female Erins. More are female than male, though not unheard of for a guy.
Several decades ago (in the 70’s and 80’s) I worked with a male Shannon. Then in my next job (in the 2000’s) I worked with a female Leland. I never asked how their names were chosen.
I know two Ulysees under age 3. They go by Uly – yoolee.
Hmm, the only Erin I know is male, and I assumed it was a traditionally male name!
I know both male and female Lindsey’s and Tracy’s.
Have not read much of the thread, but to answer the question posed in the post title…if you like name, say so. If you don’t like the name, simply find something else to comment on (“we’re so happy for you!” or “what a beautiful baby!”). This seems like basic manners 101…
I know a lot of Erin’s including some family members, never met a male. It’s obviously a popular name in the Irish dance community but I don’t think I’ve seen a male Erin on the competitors lists. I’ve never met male Lindsey’s or Tracy’s.
Erin was a popular girls name in my circle. I also grew up with a male Tracy but most in my peer group were women. The only Lindseys I know are also women. The first time I heard Lindsey for a man was Lindsey Graham.
The traditional male spelling is “Lindsey” and “Lindsay” for women.
All the female Lindsey’s I know are female, I don’t know any who spell it with an A
Naming your kid after a number is definitely dumb.
My SIL’s mom’s first name is Errol. I assume it’s a family name!
For the record, I don’t think musk has any kids named 9. That he knows of.
(sorry)
It is definitely Musk-esque to name a kid with a symbol or a number. 
Remember the tv show Blossom? Her best friend was Six - I loved it.
My mother did not like what were going to name our older daughter, “that’s a boy’s name. All I can think of is (old actor’s name).” I was pretty upset with her. She didn’t mention it more than a couple of times, but 33 years later it’s still annoying even though I can kind of laugh about it. One more of a million things that passed through an almost non-existent filter.
Our second has a name with a common British spelling. Amazing how many variations there are in the spelling.
My youngest sister was given a name that is now fairly popular, albeit with a dozen peculiar spellings. I remember going in to tell her first grade teacher how to pronounce it.
My sister has a friend who did say something (but just once I believe) initially to her son and his wife when they mentioned the first name they were considering. The last name was two syllables starting with P (think Peppey or something like that). They had a first name they were thinking of for their son (2 syllable gender neutral starting with P). She asked them if they were concerned about the kid getting teased , P P jokes, for instance. They weren’t deterred and used the first name starting with P, and then also used a gender neutral P first name for their daughter later!
When immigrants from non-English-speaking countries to the US name their kids, it does appear that the likelihood of giving their kids (or themselves) a “typical American” name is related to the difficulty of getting a reasonable pronunciation of a heritage language name out of English speakers.
One of my kids had a friend whose parents were born in Korea. They had 2 boys a couple years apart and we knew the other kid through a sports activity. They both had names that started the same way( think like Ji Hun and Ji Yoon). I kept it straight in my mind initially by thinking of it alphabetically-the older boy had the H name, the younger one(son’s friend) had the Y name , which was later in the alphabet than H.
