Ok so how can Hadrian become Lord Slytherin if the first born son gets everything? Did his Grandmother appoint him over his brother? Is it bc he has parselmagic and his older brother doesn't?

i think this story is not for me.
This story is more OC than possible.

I mean they only have the name from the series or part of it. Even Ilvermorny ... they have almost the same courses than Hogwarts. Maybe some a bit different but surly not Hogwarts2.

If you would change names of some parts you had your own story.

But it is not the only thing I do not like... hm okay it is not really a dislike it is more so that you continously set Illvermorny against Hogwarts even if it is not needed. I mean he goes to this school ... seems to be a genius since everything is easy and too fast ...

I thing you would have needed Hogwarts only if there would be a meeting between the school at this moment like: we have the tri wiz but rather than France this time with the American counterpart Illvermorny.

if they would show there that the students now much more than okay but previous it is not needed since Harry won't have any idea what Hogwarts is about.

This is turning out to be an interesting story and a different take on most fanfictions. good luck and keep up the good work. be safe in this times.

Where do I want to start? Voldie was vanquished when Harry was 15 months old, not a few months after being born. At a few months, babies are not aware enough to know there is any danger, so a rebounding AK wouldn't make any sense. Why does everyone feel the need to change Harry's WHOLE name. Hadrian is OK (I rather like it), but many authors such as you give him a complete name change, so he's not really Harry James Potter, he's a complete OC.

So I'm guessing this is a see the future but can't change it story, otherwise Daisy would have at the very least saved both her grandchildren from Dumbledore's clutches.
It sounds odd when the goblin called Daisy "Daisy" instead of Lady Slytherin, I always saw them as very particular about titles.
Is Andromeda still married in this story and does her daughter Tonks still exist?
You might want to change "diviner" to "seer", people think of searching for water or mucking around with chicken guts when the term "diviner" is brought up, unless that is what you are going for.

Good start. The way you described the birthing scene made it seem as if the entire family and all their friends were in the delivery room watching Lily give birth.

It is recommended to read out loud your finished work, it makes errors stand out.

Not sure why she needed Andromeda's help but I am looking forward to them living in MACUSA territory.

You need to use complete sentences. A lot of this is one long sentence that manages to stretch across the entire page. it makes this very hard to read and follow

Use “memoriās” for plural accusative/object “memories” because “sēnsus” means participle “perceived.”

Cannot wait to read more! ;o)
