Dear Janice:
You will find 1901 census info for James Dalton (born August 28, 1845 in Ontario, Canada) & Mary Ann Collins (christened March 28, 1846 at Templetenny parish Catholic Church, Ballyporeen, Tipperary, Ireland) & their children at
http://www.archives.ca/02/02012202_e.html , if you check Ontario & go to Victoria (North) District 119 Subdistrict Galway (i-3) Schedule 1 Page 2.
Please note that while Mary Ann Collins' brother Patrick Collins (Mar 13, 1835 - Jan 31, 1914) was the enumerator for the census, he tended to make spelling errors & to change birthdates to make people seem younger than their real age. Also note that Galway township spans both Victoria & Peterborough counties when looking for information.
The 1891 census info was online (last time I checked) at
http://users.rootsweb.com/~ongenpro/census/transcript/Peterb... .
You can search the 1881 Canadian Census on the Mormon website at
http://www.familysearch.org, but note that the family name is misspelled DAULTON on the census or transcription. You can find a complete searchable transcription of the 1881 Canadian Census for Galway & Cavendish townships, Peterborough (East), Ontario here.
The 1871 Canadian Census for Ontario is indexed online at
http://130.15.161.100/census/index.html or at the National Archives website
http://www.archives.ca. You'll have to look up the microfilm at a local library to find out details. I think it possible that James Dalton's father & brother may be listed on this census in Dummer Township, Peterborough County, Ontario.
I have more info if you would care to email me. If you are a descendant of Mary Ann Collins & James Dalton, then we are related & I would appreciate any info you could share with me.
Thank You.
PS My parents noted that four sons or grandsons of this family settled near Wainwright, Alberta.
