Fairly certain it’s the follow-up song to Nathan’s ‘Mary’s Child’.

‘Mary’s Child’ tells the story of the French who came to bring Christianity to North America, but who also brought smallpox, which decimated the First Nations peoples. In the song, Mary was one of those First Nations people who died during, or shortly after, childbirth. The child was taken back to France following the death of his mother.

Mary’s Child (Nathan Rogers)

I spent a very pleasant evening with Nathan a few years ago, and we talked about Mary’s Child (which is a song I sing/play) and The follow-up - pretty certain the song in the thread tittle is it.
