Lurgan First Presbyterian has the following
Joshua Follas and wife Jane McKague of Lurgan baptizing George Sept 8, 1832 but later saying he was born Nov 7, 1832. Francis was baptized Dec 19, 1835 and Joshua's wife was Jane McTeague then.
On Sept 1, 1843 Samuel Folsa and Margaret McKeag had dau Margaret Jane. I assume that is Folas and don't know if Samuel married a sister. They lived in Portadown. 'J' and "S' look very much alike and I am reading from someone's transcription. It is a strech to say this is Joshua again, but it might be.
Thomas Folless and Elizabeth McDowell, Lurgan weavers had dau Mary April 17, 1846
Richard Fellis and Charlotte Thompson had Elizabeth Mar 31, 1861 and Sarah ann Feb 28, 1863, baptized together
A very early baptism of Eleanor to Thomas Folleur or Felleur born and bapt Aug 20., 1769 might be a Follas, but there isn't another similar name before the early baptisms end.
Not at that church:
The above Richard and Charlotte were the parents of Margaret who married David Archer. It was my understanding David married Ellen McCullough in Shankill area on Dec 23, 1877 and had Mary Ann in 1878. I thought this was the David Archer who remarried a Follis. If you have the marriage record, whom do you have as a father?
