I'm revisiting a question I asked two years ago.
The situation revolves around these two bits of information:
In the 1870 US census for 1st Ward, Fremont, Sandusky, Ohio.
Engert, John, 54
Williamson, Clara 16
This data matches the research my mother did before I inherited the database. The Williamsons are niece and nephew to Anna.
In the 1880 US census for 2nd ward, Fremont, Sandusky, Ohio.
Engert, John, 64
Anna, 63, wife
Mary, 23, daughter
John Jr., 21, son
William H, 16, son
Magdelena, 9, daughter
A general feeling from the previous question was that the William in 1880 is not the same person as the William in 1870. Indeed, there is a separate census record for the elder William. A big reason for that belief is that Anna would have been in her late 40s when this William was born, and in her mid 50s when Magdelena was born.
One possibility is that the younger William and Magdelena were adopted. Another is they're some other relative, such as great-neice and great-nephew.
I've searched the FamilySearch Ohio Births Database and didn't see any matches for an Engert child born in or near Fremont a couple years before and after 1871.
Where might I search for more details about the younger William and Magdelena?
I also noticed that John Jr. does not show up in the 1870 census at 11 years old.
John's early life has always been a puzzle. The census records say he was born in Baden. I have a record saying he came to America in 1839 and married Anna in 1845. I don't know of any siblings and don't know his parents.
The ID below is for Anna.
