I came across a set of videos about Yung Wing on the Chinese website 56.com. I believe they are online copies of a documentary that was aired on TV... I am not certain, though, as they are in Chinese and my understanding of the language is limited. If anyone is willing to translate them for me (and for this website), please send me an email (email@example.com). Meanwhile (especially if you understand Chinese!), check out the links below!!
In response to an email I received, I catalogued a number of addresses related to Yung Wing in Hartford.
Yung Wing's grave can be found at the Cedar Hill Cemetery: Cedar Hill Cemetery 453 Fairfield Ave Hartford, CT 06114 (860) 956-3311
Yung Wing was married at the Asylum Hill Congregational Church, the church of his good friend Rev. J.H. Twichell: Asylum Hill Congregational Church 814 Asylum Ave, Hartford, CT 06105
The Chinese Educational Mission building was located on Sumner Street and then, more famously, on Collins Street. I am not sure what became of the temporary Sumner address, but the Collins Street location is now a hospital: 352 Collins St. Hartford, CT 06105
The Hartford City Directory of 1875 lists Yung Wing's address as: b. Park Central h. It is possible that Park Central refers to the Park Central Hotel that burned down in February of 1889, once located at: 54 High St. Hartford, CT 06103
In 1880, Yung Wing was living with his wife's family. I have an address for Bela Kellogg, Yung Wing's father-in-law, though, I don't believe the house is still standing: 3 Chapel St. Hartford, CT
A Chinese documentary about Yung Wing and the Chinese Educational Mission came out about two years ago. I just found a series of articles (in English) about the project on CCTV. I'm posting the links before I've even had the chance to read them, but all eight promise to be good!
Joseph Twichell, Mark Twain and the Chinese Educational Mission, 1872-81
An interesting essay just as much about Mark Twain's relationship with the Chinese Educational Mission as it as about the Mission itself can be found here. I happened upon it like I happen upon most things, by accident while doing related research. Enjoy!
I came across this website while googling for a news article I read a few weeeks ago. It's right down the ally of this website--a blog written by a graduate student studying late Chinese history. This article, in fact, is on Yung Wing and links to The Yung Wing Project.
