Frederick Zeller

I am looking for more information on Frederick Zeller,don't have a birthdate but he passed away in 1838, in Juniata Co. PA The children were: Henry,Magdalena,Betsy,Barbara,and Anna Catherine, my ggggrandmother married to Peter Riehm (Ream). She went by Catherine not Anna. I found this out by the census and on her headstone it is Catherine also.
