I was born in Manhattan, in NYC, so not naturalized. The addition of a middle name was voluntary, not related to marriage or any other external impetus. Unfortunately, my mother passed away some time ago, so cannot advise me on this. I remember going to the court for the name change (addition of middle name), but I do not remember the exact year. I am fairly certain I was around 10 or 11 years old, which would have been 1968-69. This past week I went to the county and city clerk’s offices in Manhattan to try and find the record. They had me search through the old name change books from those periods (and several years before and after) – those records are not digitized. I did not see my name in those books, and they didn’t seem to have any other way of locating the record. They suggested I try Brooklyn, but I am pretty sure we went to a court in Manhattan, as I only lived in Manhattan until I left the city. We lived in various places in Manhattan when I was growing up – the most likely places are Cornelia St. in the Village, East 4th St. (in the East Village). Unfortunately, I don’t remember the exact street addresses, although I might be able to find out that information.
