Hi Frances,
You state that marriages and baptisms were submitted to be recorded in 1847. You also note that the Catholics were not legally dissenters and that they generally were buried in the Anglican cemeteries.
Would the Malew Church have records of these burials with more than just the names of those interred?
I wonder whether the Catholic autorities would have records of their adherents which may provide a link to these unfortunates' family?
Perhaps they receive a lot of similar enquiries, they certainly ignored mine.
Cheers
