My Great Aunt Margaret married a Edward Langrell in 1923. Her maiden name was Murray and during my childhood I lived with her and my mother on The Mall, Wicklow. This Edward, or Ned as I knew of him, died in Sept 1945 aged 54. His father was Issac Langrell who died in Nov 1929 in Wicklow aged 70. I know Ned had a sister Margaret (Mag) and a brother William (Bill) who both lived in a house in Market Square Wicklow. It was a Protestant family, although Ned married into the catholic religion when he married my Great Aunt.
I hope this helps
