Hello Carolyn, If you look at the label at the top of the column in which "Pa" is entered, you will see that it refers to the naturalization status of the individual. The abbreviation means that Francis had filed his Petition for Naturalization, often called "final papers." Once the petition was accepted by the court where he applied, he would have gone through the naturalization ceremony and then given his Certificate of Admission (to citizenship). In that case, the abbreviation "Na" would have been entered in that column. Hope this helps, Doug Nicol -- Norman D.
