alenars on Family Tree Circles

I?m looking for information on William J STEPHENS. He was born in 1850 and married Anna RUSSELL in February 1870. They are listed in the Henderson County, IL 1870 and 1880 Census. I found William in the 1860 Census. He was living with the Vaughan family. William died, I believe sometime after 1894. Anna moved all her children to Lawrence County, Indiana by 1900 Census.

Who are William?s parents? If the 1880 census is correct, his dad was born in Pennslyvania and his mom was born in Ohio. It could be correct or incorrect information. If it is correct who does it rule out? Last name could have changed? William?s birth year in 1850 could be incorrect? William?s middle initial could be incorrect? The J could stand for Joseph, James, Jacob?

What year did William die?

Where is William buried? Might be southern Illinois.

Their son William Asberry must have been named for William A. Vaughan that William J STEPHENS lived with in 1860 and next door in 1870.

Was the Vaughan family related?
Or did they just foster William J. STEPHENS?
