I have found in the 1930 census a person whom I believe is a relative of
mine, born 1894. The wife's name, his profession and the neighborhood all
seem to be a match. The only catch is that the relative is named Harry, and
his son's name is "Harry, Jr.". The last name is BREINER, which can be
Jewish but can also be German.
What is the likelihood that a Jew (born and living for his first 8 years of
life in a shtetl), would call his son, born in NYC, by the same name?
