Bray RC parish records are available on the Irish Family History Foundation website at :
www.irish-roots.ie the index is free to search once you register. I believe the records are a complete extract of the Bray parish as per microfilm no P.9371 in the NLI
there does not seem to be a good match for the names you mention
Luke 15 matches in Co. Wicklow, none for Bray parish
William 9 matches in Bray parish, but none have father listed as Charles
Edmund no matches in Co. Wicklow
Peter 4 matches in Bray parish, but none have father listed as Charles
Lawrence no matches in Bray parish
