Hi I am reseaching the Mathieu, Matthieu family,I have alot of names on my data base,. Would love to share with you. My family added the extra "T" in Matthieu, we do descend from the same Jean Mathieu.
My Matthieu family came to Oregon in the 1840s. My grand father was in Oregon History. Francois X. Matthieu born in 1818 in Canada.
