Thank you so much for answering. I had about given up hope of hearing from anyone. My grandmother was Matilda Bergersen Persels, a sister of Gustave who married Nellie Baird. I have a picture of Frank Wooldridge with the Bergersen children. If you do not have that picture will be glad to send you a copy if you will give me your Email address. Mine is MVoss730@aol.com. I have tried to find out more about Nellie and her family in White County, Illinois to no avail. Frank's family is easier to trace.
