SENIOFREDO, son of BORRELL & his wife --- (-killed in battle 849). Emperor Louis I granted "villam…in pago Narbonensis…Fons-coopertus" to "fideli nostro Sunicfredo" by charter dated 829, which states that "Bosrello patri suo" had previously held the property[57]. He established himself as count in the area known as the "March of Spain", south of the Pyrenees. He apparently led a revolt of the indigenous [Visigothic] population against Bernard de Septimanie (father of Bernard "Plantevelue")[58]. He conquered Cerdanya and Urgell in the 830s, checking the Moorish expansion. He was killed in a counter-attack by Guillaume, son of Bernard de Septimanie, in 849.
m ERMESENDE, daughter of ---(-[after 1 Dec 885). A charter dated 22 Mar 865 which records a judgment in the court of "Salamon comes in castrum Sancti Stephani" in favour of the abbey of Lagrasse recites prior donations by "Sunicfredo comiti…cum uxore Ermesinda"[59]. "Ermessinda comitissa et Rodulfo comite et Mirone comite et Quixilo comitissa" made donations by charter dated 1 Dec 885[60], which is assumed to refer to Ermesende, widow of Sunifred, two of her children, and the wife of the second son, although this is not without doubt.
Comte Seniofredo & his wife had [eight] children
