Look carefully at Findagrave Photos

While researching my Peckham line from Oswego, New York I briefly glanced at a gravestone photo Erasmus Peckham (1832-1879) on findagrave.  He and his wife Nancy Wooster are listed together. However (thank you findagrave contributor H. Harmych) there is a also a photo of a second stone that provided new new information.

At first I had not paged down to see this second photo and when I did, initially the impact of the information contained there did not hit me. When I decided to transcribe information about these 2 previously unknown children, the death year 1865 seemed odd since Erasmus and Nancy married after 1870. Then examining it more closely I saw that Kittie's parents were noted as E.W. and K.B. Peckham while John's were E.W. and N.A. Peckham. Who was K B Peckham and what happened to her?
