Here's a wild theory for you.

Home in 1920: New Orleans Ward 15, Orleans, Louisiana
Age: 43 years
Estimated birth year: abt 1877
Birthplace: Louisiana
Relation to Head of House: Boarder
Father's Birth Place: Louisiana
Mother's Birth Place: Louisiana
Marital Status: Married
Race: Black
Sex: Male
Able to read: Yes
Able to Write: Yes
Image: 78

Household Members: Name Age
Paul Brown 38
Ella Brown 36
Thaddeus L Aubert 43

He is not listed with either wife or children - but is listed as married. Could it be possible daughter is named for him?

He died (pretty sure it's same person):
Thaddeus Aubert 37 yrs 30 Jun 1922 C 1046 184

Census or death record could be wrong - but there is no one else with that name in LA.

Which is about the correct age for her to have gotten pregnant with last child.

Possible?
