I am looking for the 1880 census information for the Barrett family who are probably living in Brooklyn. The family includes head of household Jeremiah Barrett (born 4/1847-age 33) an Irish immigrant (immigrated in 1867 atage 20) Janitor, wife Helen (born 4/1847-age 33) an Irish immigrant (immigrated 1867 at age 20) housekeeper/mother, daughter Mary E. (born 2/1872-age 8), daughter Juliet (born 3/1873-age 7) a bookbinder, son Michael (born 8/1874-age 5) a day laborer, John (born 2/1877-age 3). All of these children were born in New York. There is a chance there were other children born in Ireland. I am particularly interested in parents Jeremiah and Helen and any information that is available on their background in Ireland. Even the 1870 census would be great. thanks to all in advance for your help.
