History & Origin
Lonza is a short form of Alonzo, the Spanish and Italian form of Alphonso, whose Germanic parts are usually read as 'noble' and 'ready.' Trimming the leading A- left the punchy Lonza, which some families then gave as a full first name rather than a nickname.
It was never common, given to only around fifteen boys a year even at its peak in the mid-nineteen-tens, and it faded early. A boy named Lonza then would belong to a great-grandparent's generation.
