I'm trying to fill in about 70 years of our family tree.It is lost from the french revolution until my great grandmother.We had a family reunion/100 th birthday for her in about 1962.Her name was Antoinette and she tells the family story about how one daughter escaped after the revolution.The history is lost from then until she was born.She married a man named Patrick Francis Mc Dermott who was born in county mayo,Ireland in 1860-1865.We don't know the whole story,but my great grandmother showed me the family "Carte Blanche" card to prove her stories were true.Any help would be greatly appreciated. Thanks
