Simcha Assaf, in an article in Volume 5 (1933-1934) of the journal Zion on Anusim of Spain and Portugal in the Responsa Literature (Hebrew) wrote (pp 20-22) such statements as (loosely translated) "at the time of conversion every convert received a Christian [given] name and even their family names were changed, and the government enforced that converts should not use their Jewish name, and would punish for doing so." He cites the Ribash, who made such a statement (so that would be before the Inquisition). There are other statements along these lines that he makes regarding names of conversos, with citations in the responsa literature (the point of his article). I'm looking for corroborating material - is there other evidence that conversos were obligated to change their names - particularly their given names, or was it actually a phenomenon more in line with either being a sincere convert or wanting to hide one's continued secret Jewish identitly by taking a Christian name? Testimony abounds about conversos, many who were true anusim and came out as Jews when they could, who had Christian names (and often retained their Jewish names). But I'm looking for any evidence for something methodical, official. And any detail about which names might be accepted (for example, Abraham is a no-no, but maybe David is OK) would be of interest.
