George Henry Hartzog was married 3 times.1st to Sarah Tyler - (uncertain which of 2 posibiliites was her parents.)His second wife was Eleanor Reed, there were no children, it is believed she died in child birth.Celia was his third wife.
Celia's father was Barnabus Baxley and her mother was Mary Stevenson. Celia's Half-brother James Baxley (mother was Rachel Unknown) married Rebecca Hartzog, daughter of Daniel Charles and Elizabeth Zorn Hartzog.
If the census has William's age incorrect by at least three years, then it is also very likely that the other ages are also in error.It is also possible that , if the ages are incorrect... Martha and William could have both been born in 1837 - (if they were twins). Do you have any other proof - other than the 1850 census, which you already say is incorrect, as to the birth date of Martha or William? If the ages are incorrect, the last names could very well be incorrect also!
Back to the real problem... Is there any documentation proving that George Henry Hartzog was the son of Daniel and Susannah Zorn Hartzog?Did Daniel or Susannah leave a will or any land transactions that might list their heirs?
With so many of the Harzogs and Zorns being first cousins - and double first cousins, and having the same names, this can get very confusing. John Phil
