O’neill ancestors of Puerto Rico . I was recently doing research of the O’neill’s living in Hato Nuevo in the 1800- 1900’s. My grandfather is Gregorio O’neill Rosario (1895) and My Great Grandfather is Juan O’neill Santa (1866) or (1880). Looking at the different census’ of 1910 -1920 -1930, and seeing the different neighbors that surrounded my relatives I can only assume that all our families are genetically intertwined. Well im really interested in finding information but I have basically been stuck with Juan O’neill Santa, I find absolutely no record of him after the 1920 census, In 1930 his wife, Getomino Rosario Camareno de O’neill was part of the census with only the O’neill children. I found some passenger lists records for a juan O’neill on a ship called the San Lorenzo departing to NY 10/8/1923 but I don’t know if it was him. I found some social security death indexes for a Juan O’neill estimated date of birth as 1866, that to is questionable. Can any provide any information regarding the above O'neills.
