I started this bit of research to see if the Crowley family of modern day Fenit were living in Fenit in 1853. This was not the case. However, they were not far away!
I extended my search to the Civil Parish of Ballynahaglish and found the following;
Crowley, John-Ballygarron (townland) Number 7
Crowley, Laurence-Ballymakegoge Number 9
Crowley, Mary-Tawlaght Number 1
(Fenit is just to the left of Number 1 like the pointed toe of a shoe.)
