Hi, Cynthia! I'm Christina Michaelis, Greg's daughter and Polly's granddaughter. I've been researching the family tree, and have gotten stuck at Polly's grandparents, who I believe were Zissimos Typaldos and Marjorie (or maybe Mary) Psiaki. Do you have any information further back? How are you? I hope you all are doing well. It's a shame that without Grammy to keep the family together we have not kept in touch.
