I found some McCabe records in Old St. Joseph's RC Church in Philadelphia, PA...probably too early to be your guy but this is what is listed:
Charles McCabe married Sarah Murphey and had a daughter Elizabeth born 16 Apr. 1795
John McCabe married Mary Elgin and had a son Thomas born 13 Sep 1795.
There is also a Mary Macabe bapt. 20 Dec. 1772. The parents' names are not listed.
You might want to check with the American Catholic Historical Society in Philly to see if they have any additional records since we now at least know SOME McCabes were living in this area and in the Catholic Church records.http://www.amchs.org/
