I am also looking for any information on the Worcester Mathieu's. My Pepe (g-grandpa) Was William J Mathieu (1907-1987) he married Gladys K Johnson. His Father is Joseph (1874) and mother is possibly Delina. I believe but am not sure that Joseph's family came from Canada but we have him as being born in Mass.
If anyone has made any head way with this line could you please help? Thanks!! Heather
