Assuming some of your Cullen relatives remained in Wicklow, I took a look at the 1901 census which shows around 716 "Cullen" as living in Wicklow. You may want to review the site to see if you can zero in on a smaller area within Wicklow. http://www.census.nationalarchives.ie/search/ I have been researching "Miley" in the townlands around Carrigacurra and Valleymount and have come across Miley & Cullen marriages. In the 1901 census there were 20 "Cullen" in the DED of Togher which covers the towlands arround Valleymount. Hope this helps Pat Morgan
