Hi Chris,
There are 3 grave yards attached to Knockbride, 2 in East & 1 in West Knockbride & West Knockbride is the graveyard you need. It is situated in Tunnyduff. The current priest may not be the best to approach, he covers both churches in Knockbride.
To get your research off to a quick start, seeing as you are coming in September, I think you should contact Cavan Genealogy
Civil registration records are available from the General Register Office (GRO). These start from 1864. You can access the website here:http://www.groireland.ie/research.htm Or you might try Valuations office in Dublin (http://www.valoff.ie) which will have a record of the land registry from 1855 to modern times. This will assist in seeing what happened to any land the familymay have owned (as it usually passed on to a relation).
