Shirley Hofacker Missed in 1920

Who were the children of Florence Lutter (1892-1983) and Adam Hofacker (1893-1974)? A mistake in the 1920 federal census might lead someone astray in this inquiry.

Florence and Adam were married in Newark, Essex County, New Jersey in 1915.

Bride's parents- Charles Lutter and Annie Lau.

The couple appeared in the 1920 federal census in Newark with two children. Their daughter, Mildred, was age 3 and 5/12. Her calculated birthday would be around the middle of 1916. Their son, Charles, was age 1 and 2/12. His birthday would be in October or November of 1917.

Adam Hofacker, head; age 27.
Florence, wife, age 27.
Mildred, daughter; age 3 years and 5 months.
Charles, son, son; age 1 year and 2 months.

In the 1930 census, the family was still in Newark. Their children were Mildred, age 13, and Shirley, age 11. Charles was not listed.

Florence, wife; age 37.
Mildred, daughter; age 13.
Shirley, daughter; age 11.

Charles would have been eleven years old at the time of the 1930 census. The absence of a child in the enumeration of a family could be in error, but usually indicates that the child died. The index of deaths exists for 1920 through 1929. No good match was identified for this child.

The index of births in New Jersey has an entry for Charles W Hofacker, born in Union County on April 23, 1918. This is near Newark. This person was the son of Charles Hofacker and Anna Kurz. The parents were with Baby Charles in the 1920 census, along with Dorothy, their older child.

The birth certificates of these children are housed at the Archives in Trenton.

In 1939 Shirley Hofacker married William John Geerke in Irvington (city next to Newark). She died in 2013. I found a notice of her death in Florida, but that is all so far.

It would appear that the entry of Charles as a son of Adam Hofacker in the 1920 census was in error. I submitted a request to update to this entry on Ancestry.
