Hi, I am trying to prove who my great great great grandfathers parents are. His name was John LaDuke( maybe Jean Baptiste Leduc?). Born in May of 1825. Married Mary Casilda Rosa Wattier in Ogdensburg N.Y. on 9 June 1850 and Died March 1913. He was born in Canada. I was told his father was Francois LeDuc , possibly Francois Celestin LeDuc but with no mother's name , I am stumped. none of the sources I have found have this info on it. Francois was from France on one form and on another from Les Cedres Quebec. Can anyone help me?? Anne
