"Hear of" = you get information ABOUT that person or thing. "Hear from" = you get information directly FROM that person.

*Hear of: to receive news about someone/something They have a new baby! Why haven't I heard of this? I was shocked to hear of her death. *Hear of: to be aware of the existence of someone/something I've never heard of him. Have you? *Hear from: To receive information from a person via mail, email, phone call, or direct conversation. If you don't hear from your sister by Friday, call her to make sure she's okay. Have you heard from Kelly? I haven't heard much from them this year. I hope this helps!

Is that "Hear Form" as in "Form"? Or do you mean "From"? Either way both seem really difficult to make out into a full sentence. I would either use "Heard of/Hear About" or "Hear From/Heard From"

And “hear about “?

"Hear of" = you get information ABOUT that person or thing. "Hear from" = you get information directly FROM that person.
