There is a strange type of endemic nationalistic racism in Ireland which denounces anybody who deserts Ireland. However, if that distant ancestor was deemed a debtor to the 'Crown', meaning the thieving agents of the yukky uk'ies and was banished to a distant colony like Oz, NZ, america, that family can come humbly back, shut their mouth and not bring that subject up and remain in Ireland, the locals will forgive you for deserting ye olde sod.
Another category of folks forced into the yukky uk'y army or navy by being seized on the street by impressment gangs, can also come back and not bring thesubject up. Unfortunately, so many hybrid wanna-be Irish-americans brag about the better life they found in the U.S, these 'e-jits', actual word idiots, have created the present conundrum of once gone from Ireland, you lost your right to consider yourself Irish.
This perverse, sadistic mentality exists in every country on the planet where those trapped behind, who couldn't afford to escape, make life miserable for any returning Irishman. It happened to my grandfather who was 1st to leave the family hearth in Carrowmacbrine Sligo.It was even worse 'cuz he came back in the late 1920's, after the Irish Rebellion created the Irish Free State. Those who left were considered traitors.
Our specific Hanley family resided on the same farm if Hanleytownship, Carrowmacbrine, Sligo for over 500 years.
