I stumbled upon an 1840 census record for a Jemima De Lauche (head of household) and family for Detroit.
I have no idea if Jemima and family are related to my Canadian De Lauche (sometimes spelled Delauche) family line or not.
I am just posting here in case someone is researching the family.
Synopsis of the info:

Jemima De Lauche (head of household):

White Males age 50-59 – 1
While Females age 5-9 – 1
