Alfonce is of Germanic origin, derived from the Old German 'Adalfuns', which means 'noble and ready'. It consists of two elements: 'adal' meaning noble, and 'funs' meaning ready or prepared. This name was popular among the Germanic tribes during the Middle Ages but has since become quite rare. The closest modern equivalents might be Alfred or Adrian.
"The name Alfonce was relatively popular at the start of the century, with a peak of seven births in 1914 and declining slightly thereafter."
