First, I discovered that Alice, the mother-in-law of my cousin's daughter, Nancy had a relative who married into the family that ran the Mandarin Restaurant in N. Y. (described by Gilroy Chow in Sweet and Sour) that Gilroy's father ran.
The next day, I met Winnie (Yao) and her mother, both who knew John and Lancy Wu whose Canton Restaurant in Savannah was depicted in "Sweet and Sour" by son, P.C. Wu.
What a small world indeed!
