Hi Mary . .
Our . . Mallow Cork volunteer . . has . . in all probability pinpointed your relative . . well done to them . .

When I looked at your search query . . . the locations . . Ballinakill, Queens Co., , indicated an area here . . close to the town of Roscrea . . . and I searched for clues . . . but failed to add to the search . .
The surnane " Mealin " would be uncommon to this area . .
But . . I will alert the volunteer who sits in the . . Ballinakill, Queens Co area . . to have a second look . . .
Cheers . . Eamonn Horan
