This compilation contains information on 7,414 of the first families to arrive in New Brunswick. Each descriptive family entry contains the name of the head of a household, his date and place of birth, the date of his death, the names of his parents, and the name of the community, parish and county where a family settled. Next is listed the date and place of marriage, the name of his wife, the date and place of her birth, the date of her death and the names of her parents. The names of each of the children, their dates of birth and death, the names of their wives, their dates of birth and death and names of their parents are listed. The family entry concludes with a description of the record source or sources at the Provincial Archives of New Brunswick in which information was found. The name of the file, the book, manuscript or collection as well as the number of pages within the source or sources are provided to enable the researcher to visit the Provincial Archives and locate this material quickly and efficiently.

Researchers should remember that the data in each descriptive entry is only for the first family of that surname to arrive in New Brunswick. Information on the family before it came to New Brunswick, and for succeeding generations sometimes up to the present, may be found in the file, book or collection. The genealogist will have to visit the Provincial Archives and check the resources out for themselves. Acadians, Pre-Loyalists and Loyalists who arrived in the province with older children who immediately married and themselves began having children may have two generations of their family described.

Since the information in First Families is contributed, it is the responsibility of those who use the information to verify its accuracy.
