Siamese (conjoined) twins are rare: about 1 out of every 50,000 to 100,000 births. But, while doing research on the descendants of my 3rd great-grandfather John Pegoda, I discovered the birth of Siamese twins in my extended family.
On 23 Aug 1952, Vaudine Colburn Pegoda, wife of Casey W. Pegoda (my first cousin thrice removed), gave birth to a set of conjoined twins. The death certificate indicates they only lived for 13 hours. The twins are buried in Ebenezer Cemetery outside Huntsville, Texas. When I am in Texas again, I plan to visit the Huntsville Library and see if I can track down a newspaper article about the twins. I am sure there was one in the Huntsville Item as this is quite a rare event.
