George Johnston, where from?

[Peggy13]

I have another George Johnston from Co. Fermanagh who married Eliza Irvine Mar 15, 1849 in the Registrar's Office, Town of Enniskillen, District of Enniskillen, Co. Fermanagh. His parents are believed to be George Johnston and Susan Elizabeth Armstrong of Drumkeeran. But George was not living there in 1849 when he married and I cannot make out the residence of either George or Eliza. Sorry, I  don't know how to do a snippet. This record is from irishgenealogy.ie. Can anyone help with the residence of both of these persons?

Thoughts about the residences written in the 1849 marriage.

Maybe for Eliza Irvine - Tullycreev(e)y in the civil parish of Devenish

…and for George Johnston - Town of Lisnarrick, ? Derryvullan (and Islands) civil parish

Drumshane townland (covering part of Lisnarrick)

Thanks KG. Now that you mention  Lisnarrick, I think you are right. I was lost before. All of your suggestions are plausible and seem correct.
