Dear Patricia ,
If you go to The PRONI ( Public Records Office Northern Ireland) and search their records :
http://applications.proni.gov.uk/LL_DCAL_PRONI_ECATNI/ResultDetails.aspx
should get you there - the ref is MIC 26 if you get lost. You will find an interesting letter from a relative of my wife's family (Mcelderry) which has references to the Col.
Yours Finlay
