Have you seen Ros Davies website freepages.genealogy.rootsweb.com/~rosdavies//SURNAMES/C/Cromie.htm
a search for Loughinisland becomes interesting even though the possibley wrong spelling.
In case your Crombie is historically also Cromie, then there are family manuscript trees in existence but they may not be relevant at all Some examples are in volumes 1p84 Dublin Montague,vol 11p99 Seafin Clough, vol 22p154,vol 30 loose letter, vol 37. These volumes are in the Blackwood Family history manuscript trees in LinenHall library, Belfast. I suggest you ask them for photocopying estimates if they think your knowledge relevant and be prepared to pay the extra for post and packing. However if the material is really relevant when you get it, I suggest a further donation to this unique library that is always needing extra funds.

Loughinisland has been researched by I think the same Mr Blackwood as mentioned above.
Must go, good luck, Jim
