Thomas of Lesbo should be Thomais of Lesbo. The saint is a woman. See http://www.arimathea.co.uk/thomais.htm
Abelard is the incorrect name here. Abelard was indeed a cleric who became notorious for his affair with Éloise. Both of them later entered religious life, but no one maintains that he was a saint. The correct saint for January 3 in Western calendars is Adalard, or Adalhard.
