Hi Charles,
I came across this family and I proposed a merge of Charles Joseph Doiron with his duplicate Charles Doiron before I saw your question. His wife Florence Marie Marguerite is also a duplicate as well as a few of their children. I have proposed merges. Once they are merged, the profiles that you have created will be connected to their ancestors. WikiTree is a global tree, not a set of individual trees. Very often, especially for people who lived before the 1800s, their profiles already exist. It is important, before creating a profile, to search for an existing one. They may have the same or a similar name and same or close birthdate. Sometimes the birth and death locations differ if they are unsourced. To search for a profile, you enter the person’s name in the search boxes at the top of a WikiTree page. Then sort by birthdate and scan the relevant time period for similar names. If you do not find a match, you can try with the spouse’s or the parents’ names.
If your question was about Regina, yes they should be merged.
If you need more information, do not hesitate to ask. We are always happy to help.
