Some of the birth years at his site are out. He lists a couple of names with email addresses as his source of some of the information. It appears that the Peters family is a not a direct connection so he may not have done much personal research. I sent a message to him through his website telling him about this thread since there does appear to be some new information that we have found on the family.
There is a picture of the grave of Anna and Titus Card at the site and it has a birth year for Anna of 1870 but grave markers have been known to have the wrong dates on them. They were buried in the Camrose Cemetery. Here's a link:

He was listed last in the household of Anson (50, Ontario) and Eliza J. (40, Ontario) Peters. Here's a link to the image at Library and Archives Canada:
http://data2.collectionscanada.gc.ca/e/e327/e008174659.jpgBesides being listed last, Andrew's religous affiliation (E Methodist) is different from this Anson and family (Church of England) so I think it is a safe bet that Andrew wasn't part of their immediate family.
I've found a death in the Ontario deaths database for Emily Peters who died 25 Aug 1875 in Olden, Frontenac County. Her age is listed as "not given" and the informant is listed as Anson Peters, husband of deceased. It seems quite possible that Emma and Emily are one and the same.
I also found a death registration listed at LDS Labs site for John A. Peters, son of Anson Peters and "Milando Wagner" who died 1 Jan 1938 in Mount Vernon, Skagit County, Washington. There isn't an image but odds are pretty darn good that "Milando Wagner" is Malinda Wagar.
I've found three of the children on the 1900 US census in McHenry County, North Dakota as follows:
Schuyler Wagor, head, 32, married 2 years, born Dec 1867 in Canada, parents born Canada, immigrated 1892, farmer
Effie Wagor, wife, 17, married 2 years, mother of 1 child, 1 alive, born May 1883 in North Dakota, parents born Canada
Grace M Wagor, daughter, 7 months, born Oct 1899 in North Dakota, father born Canada, mother born North Dakota
Norah D Peters, sister-in-law, 9, born Apr 1891 in North Dakota, parents born Canada
John Peters, brother-in-law, age is listed as unknown and the rest of the columns are blank.
This would be easier if this family didn't seem to have such an aversion to registering BMD events.
