1. A good Haliburton County History and Genealogy source I use frequently: http://www.ontariogenealogy.com/Haliburton/index.html
2. The Haliburton County, Ontario wikipedia is: http://en.wikipedia.org/wiki/Haliburton_County,_Ontario
3. Some links at Genealogylinks.net: http://www.genealogylinks.net/canada/ontario/haliburton-county.htm
4. Good place for out of area/country genealogists looking for place descriptions for "Villages, Towns, Cities, Townships, Counties & Districts" in Ontario, Canada: http://www.geneofun.on.ca/db.php?database=onlocator&template=onlocator-results.html&sort=PLACE&search=COUNTY&max=200&find=haliburton&searchmode=s (Haliburton link - main site is for all of Ontario). A plus is that they solicit anyone to add any places that may no longer exist so the base grows to cover forgotten villages. For instance I have ancestry from Elsie, Ontario (used to exist between Minden and Carnarvon Ontario) so I added it.
5. For all of Ontario, a source is "MARY'S GENEALOGY TREASURES": http://telusplanet.net/public/mtoll/ontario.htm
6. A Rootsweb mailing list for anyone with a genealogical interest in the county of Haliburton, Ontario, Canada: firstname.lastname@example.org
