Unfortunately RC records for that area do not start until the 1860s.
I checked the 1828 Tithe Applotment listings for Templecrone parish. There was an AC Hanlon in Dunglow townland.
There were other Hanlons and Sweeneys. www.titheapplotmentbooks.nationalarchives.ie
I also checked the 1857/1858 Griffiths Valuation head of household listing for Templecrone. There were at least two Hanlons in Dunglow and one Sweeney (Denis) in Loughanure.
