How does the randomizer work?
Pick an origin mode, press Generate, read the receipt. The any-origin mode draws from a bank of attested English surnames. The typed modes build from documented morphemes: a trade root and an agent ending, a nature root and a settlement suffix, a father's name and a kin ending. Tap any chip to redraw just that part.
The difference from the last name generator is framing, not machinery. Both speak the same surname grammar. This page leans on the draw; the generator leans on the build.
Why random still needs a receipt
A bare random string answers nothing. A writer picking a surname needs to know what it means, because readers half-know too. Fletcher reads as arrows. Ford reads as a river crossing. The receipt turns a lucky draw into a deliberate pick.
The random last names list holds the browse-side version: hundreds of names with the same receipts, copy buttons on every row.
