Earlier this year I spent a lot of time researching my great-great grandfather Alfred McDougall's parentage, and concluded that the sources I had found indicating John McDougall was his father appeared to be more credible than three related Findagrave memorials that claimed his father was Archibald McDougall. I found no other sources for that information, and concluded that Archibald was most likely not the father. Interestingly, the Findagrave memorial itself includes the notation "Burial details unknown, specifically, connecting family." (This would indicate to me that the person who created this memorial and the two connected ones was not entirely sure the information was correct.)
I detailed all of my research on Alfred's mother Elizabeth Scholastica Dubois's profile, including the sources, and described why I believed the Findagrave information was not credible. I also listed this information on the related profiles, i.e. her three sons.
Yesterday someone came along and changed my great-great grandfather Alfred's father from John to Archibald, and offered no sources to support the change. (Interestingly, he did not change Alfred's mother Elizabeth's profile to reflect a different husband, nor did he change the father of Elizabeth's youngest son Stephen Ignatius.) This change was made despite notes being present in every related profile indicating that no evidence exists for (a) a marriage between Archibald and Elizabeth (other than the unsourced claim on Archibald's Findagrave), or (b) Archibald being the father of any of Elizabeth's children (although his Findagrave claims he is the father of her youngest son Stephen Ignatius McDougall).
In addition, Archibald's Wikitree profile echoes the death date of 1852 from the Findagrave memorial (in which the death location is listed as Michigan) but then cites the 1871 Canada census as a source. Someone named Archibald McDougall, age 70, was living in Ontario then. Either Archibald did not die in 1852, or the man in the 1871 census is a different person.
I wrote this person a private message detailing some of my research and sources that support the original father John's identity (especially "Genealogy of the French Families of the Detroit River Region" by Rev. Father Christian Denissen, page 773), pointed him to the extensive notes on Elizabeth's profile, and told him I would be interested in seeing any sources he might have to support the change in fathers. I also said that if there were no sources for this (other than Findagrave) I will change it back.
Any thoughts on how long I should give this person to respond to my request?
Also... if anyone would like to have a look at the profiles and tell me if I appear to have gone wrong anywhere, the mother's profile is Dubois-3661, and the son whose father has been changed is McDougall-3528.
