If someone is interested in this, I have recently found
much more details about Mary Teresa oo Henry Marx and their
children and also about Sophia Josefine oo Henry Granger
and their children, both families lived in Port Huron, Michigan.
I have the birth and marriage entries of the children of both families, all census entries from 1895 to 1930
and the WW1 Draft Cards for the sons of Mary Teresa.
