Al-Diri
A family name (nisba) to a place called al-Dīra or al-Dayr. Names of that kind are found across the whole Arabic-speaking world, so the nisba points to no one place.

Overview
Al-Dīrī is the nisba to a place called al-Dīra, and to a place called al-Dayr; the two are not distinguished once the nisba is written. Among the localities this reference records it answers to al-Dīra of the al-Qaṭīf oasis, but that is one of many places it can answer to, and the name gives no way of telling them apart.
A name found everywhere
This is the point of the page. *Dayr* is one of the most productive elements in Arabic toponymy: settlements called Dayr, and compounds beginning with it, are recorded from the western Arabic-speaking lands to the eastern, and the lexicon itself treats the word as an ordinary noun with a plural and a keeper's name. Ibn Manẓūr gives *dayr* with its plural *adyār* and the forms *dayyār* and *dayrānī* for the man attached to one. Add to that the second reading of *al-Dīra*, on *al-dār* and its plural *al-diyār* — dwelling, quarter, the place where people alight, from the root d-w-r — and the number of separate places that can yield al-Dīrī becomes larger still.
So the nisba identifies a class of place-name, not a place. Two families bearing it may come from opposite ends of the Arabic-speaking world and share nothing but a common noun.
On sources
The classical works this reference is permitted to cite do not document a settlement of this name in the Qaṭīf oasis. What they document is the word, in both of its readings, and the wide use of it in naming ground. No founder, no date and no history is supplied for the family name here, because none is available in those sources.
Bearing the name
A toponymic family name records a place an ancestor was attributed to — born there, settled there, known by it — as the name was applied to him, not a lineage. It attaches to no tribe, and two families bearing it need have no connection to one another beyond the word itself.
