The I slice of the verified A-to-Z index. Each row keeps the index discipline: the parts it was built from, the meaning, the origin type. The full index, all letters side by side, lives on the last names with meanings page, and the letter walk continues at the bottom of this page.
The verified index slice. The origin type stays on every row.

Which lanes own the I names
Computed from the live site, not guessed. These pages carry the most I-initial surnames in their banks:
The lane pages own each name’ s deep story; this page owns the slice. That is how an index stays honest.
The letter itself
I arrives mainly by import. Across the verified index, S is the biggest surname initial and X the smallest. The four origin engines, trade, place, parent, description, run under every letter; the mix is what changes. This slice runs 3 patronymic, 2 locative.
The how surnames work guide walks the four engines, and the European last names page maps the suffix systems that decide which letters dominate which countries.

Does this list cover every last name that starts with I?
No, and no honest index claims that. This is the verified slice: 5 rows, every receipt checked. The lane pages above carry deeper banks per tradition, and the lane pages own each name's full story. A letter page is a door, not a census.
Where these names come from.Every row is the verified A-to-Z index's I slice, re-cut by initial; the built-from, meaning and origin receipts are the index's own, unchanged. The lane map is computed from the live site's banks at build day. A row here may also appear on its lane page, which is the index's job, stated plainly. No new name data was invented for this slice.
