Making things more complex were the many former Muslims and Jews known as "Moriscos", "Marranos", and "Conversos", who shared ancestors in common with many Christians, especially among the aristocracy, causing much concern over loyalty and attempts by the aristocracy to hide their non-Christian ancestry. Some – the numbers are debated – continued to secretly practice their religions and use their languages well into the sixteenth century. Those that the Spanish Inquisition found to be secretly practicing Islam or Judaism were executed, imprisoned, or exiled.
