Joseph Drzewiecki, age 31, born in Maryland (both parents born in Poland)
wife: Josephine Drzewiecki, age 29, born in Maryland (both parents born in Germany)
daughter: Catherine Drzewiecki, age 6, born in Maryland
sone: Joseph Drzewiecki, age 5, born in Maryland
This is fairly certainly the record for the Joseph and Josephine Woods family, based on the information about Josephine and Catherine, and the fact that there are no other 1930 census records that fit.
