Hi Brian,
My great grandmother was Eliza Dowling born c1850, believedly in Carlow. Her father's name was Thomas Dowling but on some records the name appears as Dooling or Doolan. She married Joseph Quinn of Castledermot, but there is believed to have been a Baltinglass connection with them. You can see from the map how close Baltinglass, Carlow and Davidstown are. Sorry for being so vague but I've been trying to find out about the Dowlings for some time now to no avail. Trish.
