[KS] Koreans in Beijing ca. 1810

[Dr. Stuart H. Sargent]

Dear Colleagues,

I am writing in hopes that some of you are experts on Sino-Korean relations in the early nineteenth century. I am trying to identify two individuals, one or both of whom may have been Korean. Their names are 孫筠綬 and 若褱. If my hypothesis is correct, they were in Beijing around 1810 and were acquainted with Ruan Yuan 阮元, who is known to have had fruitful intellectual exchanges with Korean emissaries about that time. 

With the kind help of our Korean-language librarian at Stanford, I have searched the basic sources, but with no success. I've spent my entire career wishing I could have found time to learn Korean, but Chinese and Japanese are my only Asian languages so far, so I am dependent on the good will of specialists like you to at least point me in the right direction.

Thank you in advance for your assistance. I'd be happy to give further details on 孫筠綬 and 若褱 upon request.
