Here is the Bredimus family tree from 1695 through to Michel. There is a duplicate entry for Nicolas with years 1774 and 1776; I don’t know which is accurate.
I’ll investigate records from Bous Luxembourg when I have the chance.
I’m looking into records that Francois and Henriette immigrated in 1873, six years after Michel.
It occurs to me that Aunt Harriette began her family history with Francois and Henriette because of them living in exotic Egypt and being multi-lingual.
Probably appealed to her more than being descended from a farmer. (Michel Jean Bredimus was listed as a farmer on the Ellis Island document)
