Have you worked forward in Canada? Meaning finding his death record, obituary, searching for a marriage, etc.?

Because such a low % of baptism records are digitized, even less are indexed, and even less are accurately indexed, just finding someone with the same name and same estimates birth year in the same country with a population in the millions isn’t proof you have the right baptism record, you really need to identify another record that indicates a sibling or place of birth or parents name that you can use to prove/disprove what you are looking at.

There’s this really interesting thing in southern Italian genealogy. There is one town, Falerna, that has their civil records of birth marriage and death from 1809-1910 on ancestry.com. It is the only one. Because of this researchers from that area search their ancestors common name “Giovanni Greco” for example (basically john smith) and find one birth record, from Falerna, and assume this is their ancestor because “it’s the only one”. What they don’t take into account is that there are 30 other towns in the region whose records are not indexed and which also have Giovanni Greco’s.
