My grandmother was raised in Williamsburg, Kings County by Catherine (Nelligan) DeLeonardis. Our family had no idea that she was not her natural child until I found Catherine's will, which provided the surprising information. I had always wondered how an Irish/Sicilian girl would be named "Antoinette", and in my earliest days of genealogy research I disregarded the 1920 census note that her fater was French as an "enumerator error". I have no proof where my grandmother was born, but the census records say "New York". Sadly, the IGS/JGG group websites do not allow searching on given names without a surname, so unless I can find someone to wade through all the June 18, 1885 records I have little hope of moving forward. Your note gave me a new bit of inspiration.
