Travelling to Wexford town and to Sergeant's Lot, County Tipperary

I am planning on travelling to Wexford town (ancestral names Kirwan, Cloak, Power) and to Sergeant's Lot, County Tipperary (ancestral names Ryan, Lahey) in mid-April 2020 to visit ancestral areas and conduct research.I have already foundconfirmed parish records from 1848, 1850, 1853 in Wexford and have ascertained that my Kirwan emigrated sometime between 1854-1856 to Canada. I have several baptism records for my Ryan descendants who lived in Sergeant's Lot from 1833-1849 from the Catholic parish of Golden and Kilfeacle in County Tipperary. The Ryan family came to Canada in 1850.This would be my first time visiting Ireland and would appreciate any tips and especiallycontacts "on the ground." Thanks!
