Marriage and Children

“Of the sisters [of Old Decorah], three married Indian husbands; one married a trapper named Dennis D. Riviere, and afterwards to Perrish Grignon; the other to John B. L’Ecuyer, the father of Madame Le Roy.” (de la Ronde, 347)

“… deponent Louisignon knows that they were married by Charles Rayon about the Year seventeen hundred & ninety seven. … deponents have known said Children since their birth, and always knew them as, and believed them to be the Children of said Ecuyer and Man, na, tee, see, which said children are as follow:

Therese, now the wife of Francis Roy
Benjamin, married to Elizabeth a Menominee Woman
Jacques, married to Margaret Brunet
Simeon married to Margaret Grignon
Felice, now the Wife dead
Juliettte [probably refers to Man-na-tee-see’s daughter, Julia Grignon]”

(Waggoner, 66b)
