Ballygilgan borders Rahelly townland and Lissadell. There is some confusion whether the Diocese of Elphin Census of 1749 actually recorded Ballyminlan, Ballygilgan or Ballyweelin with a Samuel Barber and family. The script handwriting is difficult to decipher.
The next earliest records for Barbers of Ballygilgan were:
Thomas Barber, born 1811
Frances Barber, Occupant, 1858, Sir Robert Gore Booth Lessor, Land, 13 acres
No records of Barbers in Ballygilgan in the 1901 Census.
