Here is a good interview with Grandmaster Chen Xiaowang on Chinese TV. There are English subtitles.
You have to wait through a very short commercial but the interview show begins right after the commercial.
Chen Xiaowang is a direct descendant of Chen Wangting, who is credited for the creation of Tai Chi. He is the standard bearer for the 19th generation of the Chen family.
