Ruled January *1199 (H83, WARD, M) *1200 (CLARK, C40F, PAGE) to April *1231 (H83, C41, PAGE) *1230 (M).  List gives his reign as 31¼ years.  He died probably on the 3rd January (year unknown) (according to the obituary of Beauchief Abbey) (H83) and his grave slab was found *on the north side of (H79) *near (WARD) the Western nave pillar. It had a fine incised cross and an unusually short pastoral staff on the dexter side (H79, WARD).
 
He is called Tetenaye in the chronicle (CLARK), Steteneye by FOX68 and 72. He was originally a canon of Newhouse Abbey, Lincs. (H83, WARD, CLARK) and had founded Easby Abbey (Yorks) (WARD) in *1151 (CLARK) *1152 (C40, F).  Brought *8 (H79, WILLIS) *9 canons with him from Newhouse, including John de Byford (son of Baldwin friend of Peter *Gausela (C40F) *Gansela (FOX), founder of Newhouse Abbey), Hugh de Grimsby, Roger d'Alesby, (see Roger d'Alesby) and William le Sores (C40F, CLARK).
 
1212 fined for forest offences (CLARK).
 
1222 received papal mandate to inquire into the claiming of false privileges by Coventry and Lichfield diocese, together with abbot of Combe and archdeacon of Coventry, to the detriment of the archbishop of York (C41E).
 
1224 Dale Abbey given papal protection by Pope Honorius III, especially for their possessions in Ockbrook, Stanley and Depedale (C41E).
 
Some time between 1224 and *1240 (C41) *1238 (C/WC) (so this may have been during the reign of a later abbot) Bishop Alexander de Stavensby sanctioned an agreement between abbot of Dale Abbey, Henry the vicar of Kirk Hallam, and Hugh de Strelley and his wife to establish a private chapel within their house at Mapperley:  this owed fealty to the vicar of Kirk Hallam and there were to be no marriages there and no celebrations on the main feasts, when the Strelleys were to attend their mother church (C41E).
 
Matilda de Salicosa Mara came to live at the abbey when Geoffrey died – probably before 1229 (C40F)
