And for those who are researching their African/European Melungeon origins, here's and interesting link regarding African/Christian naming patterns, "Slave Ship Manifests and Slave Names". It does appear to be another blog where people are posting, however, it seems to be sponsored by a sociology department of Columbia University, as well as input from an Associate Professor, Kent State University, Ohio. There is mention of slaves having Portuguese, African, English, Catholic, Muslim, etc. names.
Although the author of this article states, [There clearly is a connection between naming patterns and ethnic/religious identity], it makes no specific mention of African slave naming patterns and how they might be associated with religion, however, it is very interesting reading.
I know it's a long shot, but have you considered trying to locate your Jewish ancestors among Catholic church records since some were forced to convert to Catholism?
