in / at / from?

Read this sentence:

The house of Sir Lee Hang-ro's birth, who was a metaphysics scholar in the end of Chosun dynasty...

I would like to make sure if it is correct to say a certain scholar was "in", "at", "from" or "of" the end of a certain dynasty...

I would say "at the end of the Chosun dynasty" (make sure to include "the" before the name of the dynasty). Also, it sounds odd to have "birth" followed by "who" because then it makes it sound like the birth was a metaphysics scholar. Maybe you can include a longer section of the text so I can see what you intended?

I actually read this from :

http://www.invil.org/english/tourism/themeTour/contents.jsp?con_no=23899&Menu_no=22038&cate=cate2&sub_no=0&page_no=1

Well, just never really figure why and when to use which preposition...

Oh, ok. Yeah the sentence that site uses doesn't work that well. For the site I'd simply put:

"The house of Sir Lee Hang-ro's birth"
[Sir Lee Hang-ro was a metaphysics scholar at the end of the Chosun dynasty]

I also think that "toward(s)" works. I might say:

"Sir Lee Hang-ro was a metaphysics scholar towards the end of the Chosun dynasty."

Just one more question, should the word "dynasty" be written in low case or with a capital D?
