I am also a descendant of Daniel. Do you have any of the information on the ancestors in France? The Sizer Genealogy compiled by Lillian Hubbard Holch indicates that Antonio's family emigrated from Lenard, France to the island of Terceira. I can find a St. Leonard. France, but not Lenard, France. Perhaps it was a misspelling or a town which no longer exists. Anthony Sizer and Daniel Sizer were both my Grandfathers several generations removed.
Thank you. Kim K.
