There are many Coras

In my great-grandmother's diaries the mysterious figure of Cora appears from time to time. Most likely this is a reference to Cora Colby of Long Beach, not the Canadian missionary to Hong Kong, Cora Haist, whose book is titled "How Great Oh God Thou Art," but then again sometimes no surname is given. In her book Cora describes traveling to China by ship in 1917, which was the same year that my great-grandparents left China by a ship traveling in the opposite direction. Cora mentions Sarah Kugler in her book. Cora describes leaving China in about 1924. We have a photograph of my great-grandparents in China in 1925. If their paths crossed somewhere along the way, I really cannot say.
