This is a new step to me! If you could go back a bit further in Enniskillen then you could possibly match up these tichbornes with the main family - which would make a lot of people very happy as this gap has proved very difficult to bridge. Some of the canadian Tichbornes began in Enniskillen too.
My suspicion is these are connected to the relatives and descendants of the London/Kent Tichbornes, who were protestant supporters of Cromwell. They incluse Sir Robert Tichborne who was Lord Mayor of London and a peer in Cromwell's Rump parliament. He was also one of the judges who signed the death warrant of Charles I - and so after the restoration of Charles II this branch would have had to hide. (Many similar families moved to Ireland - i know of the Wallers who did this and they are also related to the Hampshire Tichbornes.) Sir Robert was imprisoned in the Tower of London.
These Kent Tichbornes are separated from the Hampshire line in the 15th Century and were less wealthy (though few made some money - this branch commissioned the 17th C Tichborne spoons now in Alton museum) so their genealogy is harder to trace but much does survive and i am piecing it together now. They were in Godalming, Surrey, & Edenbridge, Kent and some direct descendants now live in New Zealand. There were also relatives of this line in Dublin about a 100 years ago.
I think someone will have to go to Ireland dig around in the archives - perhaps there are some papers of the Cole Estate. irish genealogy is a nightmare as most of the central archives were burnt in the 1920s.
There is also another branch of Tichbornes in Ireland - these are at Beaulieu, nr Drogheda, Co Louth. Descended from Henry, the fourth son of Sir Benjamin, 1st Baronet. they died out in the male line in the 18th Century but their descendants still own Beaulieu House, now open to the public.
