William F. Cody named his Springfield .50 caliber trapdoor “Lucretia Borgia.” I've seen names of rifles like "ole Betsy,  Marge, Widow Maker and Buckworth  to name a few.  As for me I christened my High Wall Quartrefoil, the ancient meaning for good luck.  How about you? BTW my pickup truck is named Maggie M'gill. LOL
