I know blockr.io works for First Bits lookups of addresses that have had a transaction, but probably won't find the addresses if they've never been funded.
You will probably have to contact the person who sold you the coins to get the full addresses. It might get trickier if they're not the first owners, but whoever bought them new should have the full addresses. If that doesn't work, contact user "
smoothie" on here, as he is Lealana, or the maker of Lealana coins.
