If you are referring to the Saturnine cult that Julie Langford mentioned, the fact that they were only present in Arcadia lends evidence to the fact that they were not numerous or powerful. Also, it seems safe to say that a good number (if not all) of them were killed by Jack and other Splicers. If there were any left after that, the probably would have joined or been hunted by the Rapture Family.
