Hi . . .
Welcome to Ireland Reaching Out . . .
Thank you for your query . . . which . . .when you stretch back to early 1800's . . is very diffacult . . . records are very scarce
back that far . . so . . . what I have found is only speculation . . . as to . . its usefulness . . but . . .
I used a search engine . . Roots . . (paid) . . . for Quirk's .. . born back then . . . for Tipperary
only three Quirk's appear from that search . . . (see below)
When I search for the surname ....Duffy . . . only TWO appear . . . (search 1828-1848) in ALL Ireland
Searched Tax rolls for 1828 and 1846 . . no real help . . .
Sorry we couldn't be of more help . . .
Cheers . . Eamonn.
