Here are the resources I've found most useful for genealogical research in New Brunswick. This page is always being updated as I discover new tools and please don't hesitate to submit additions or inform me about broken links.
Heritage Charlotte - a site that looks back on Charlotte County's history and includes links to cemeteries, censuses and more.
Marshland: Records of Life on the Tantramar - this virtual exhibition courtesy of Mount Allison University looks at life in the Tantramar area near Sackville, New Brunswick.
New Brunswick Genealogical Society - the site for the society includes forums, families histories and their First Families Index.
Provincial Archives of New Brunswick - this fantastic resource includes land records, vital records, newspaper statistics and much more. This is my first stop when researching families from New Brunswick.
