Barons and castellans · Kingdom of Sicily under the regency · as at first light, 1 January 1200

Sanseverino

The Sanseverino are the greatest Norman family of the Principato.

Their seat is the castle of Sanseverino in the Rota valley between Salerno and Avellino, and they hold the barony of the Cilento south of the Sele. Their branches hold the county of Caserta and the county of Tricarico (in the Basilicata), and one of them, Ruggero, is the cardinal archbishop of Benevento. Who led the main line on 1 January 1200, and which side the family took that winter, are not recorded in the sources seen.

Their land lies between Diepold's Salerno and the Irpinia, across the road from Salerno to Avellino.

Norman, from Turgisius, who received Rota (the later Sanseverino) from Robert Guiscard about 1061. A William of Sanseverino is dated about 1144-1190 and married Isabella Guarna, daughter of the count of Marsico. Branches: the Lauro line (the counts of Caserta, see Caserta); the line of the counts of Tricarico (a Roger of Sanseverino, count of Tricarico, sent men to the crusade in 1188); a James (Giacomo) of Sanseverino married Mabilia of Ceccano on 8 September 1188. A kinsman, Ruggero di San Severino, is archbishop of Benevento and a cardinal (campaign notes). A Jakob von San Severino was later Diepold's son-in-law (de.wikipedia: he arrested Diepold in 1218).

Where the sources disagree

Evidence: The family's lordship of Sanseverino and the Cilento is certain for this century; its head and its side in 1199-1200 are not documented in the sources seen. Do not invent a name.

On the map: The Cilento is drawn as the hill country round Monte della Stella; the barony's exact bounds in 1200 are not documented.
