278 CORNISH DEDICATIONS. 



In Bishop Bytton's Register, the designation is ''Ecclesia 

 S"Elugani," also Yllugani, 1309-10. So also in the Register of 

 Bishop Stapeldon, 1307-8. In that of Bishop Stafford, the 

 church is that of " Sancti Illogani de Logan," and " Sancti 

 Illogani alias lUugani," 1397-1403; but in the latter year, also 

 "Seynt Luganus." In that of Bishop Grandission, 1352, "Sancti 

 Illogani," also 1360 and 1366. 



S. lUogan is probably the same as the Illog of the Welsh 

 Calendars, and Illogan Parish is probably also the Landhillok 

 of the Blanchminster Manumissions. That Illog is the same as 

 lUid is rendered probable by both being commemorated on the 

 same day. There is no record of the parentage of Illog in the 

 "Welsh pedigrees, and it is therefore possible that he may not 

 have been a native. 



It will not do to insist on Illog and Illogan being identical — 

 the an is a diminutive. The Feast at Illogan seems against this, 

 as it is on October 18, whereas S. Illog's day is August 8. But 

 what does seem possible is that Illogan is the same as the Irish 

 Illadhan or loUadhan, a native of that part of Southern Ireland 

 which poured so many saints into Cornwall. His father was 

 Cormac, King of Leinster. His aunts, Feidhlem and Mergain, 

 had been baptized by S. Patrick, as had also his grandfather, 

 Ailill, King of Leinster, at Naas, in 460. 



After the death of Cormac, his son, Cairbre the Black 

 succeeded, reigned eleven years and died in 546. 



Illadhan' s sisters were Eithni and Derchartain, whom I 

 identify with Stithiana of Stythians and Derve of Camborne. 



Illadhan was a priest at Desert Illadhan, now Castle Dillon; 

 he was married, and was the father of S. Criotan or Credan, 

 disciple of S. Petrock. He belongs to a later date than that of 

 the great migration, and his settlement in Cornwall must have 

 been due to some other cause. 



In 543 occurred the plague called the Blefed, and this was 

 followed in 548 by the terrible Yellow Death, or Cron Chonaill, 

 that raged till 550. It swept Wales as well as Ireland. Many 

 saints fled across the sea with their disciples and families, under 

 the impression that they would escape infection if they put a 

 tract of sea between them and the afflicted region. This may
