>Perhaps “Paschal” is correct as this would be the Latin spelling. Remember Blaise Pascal whom “Pascal” (the programming language) was named was French. French being a vernacular form of Latin leads me to believe this to be true. See what happens when you have a Catholic Education? Everything reverts back to it’s Latin roots.
And the Latin came from the mixture of Troy refugees and Italic tribes, and is generally a leftover from the Greek, who in turn owe a lot to Phoenicians, who in turn didn't leave much evidence on who were they stealing knowledge, language and culture from...
Besides, what about the Italian form of Pasquale? I know, most of the West-European languages are actually stories on how everybody tweaked Latin to their needs and habits, but still, was there a Latin version of this name?
