[BioC] Retrieving gene name where given genomic region is included.

I have long lists of genomic regions (chr;start;end) where a given event
has taken place. These regions can be an exon, an intronic region, or
similar. Most (all) of these events have taken place within the
boundaries of genes, and I would like to retrieve the gene names
I've tried to use biomaRt:
<0 rows> (or 0-length row.names)
But since no whole GENE is within these boundaries, I get nothing. i've
also tried asking for "ensembl_exon_id" when looking at exon events (not
all of them are of that kind however), and this generally results in a
long list of exon IDs (because one exon can be part of several transcripts).
I would appreciate any ideas of how this could be done in a better way.
