Roger de Clere, III

Also owned the manor of Sinnington, in Yorkshire, and may have spent some time there. Would appear to have had no male heirs. Definitely had one daughter, Agatha (m. William le Rus), and may have had another (Amice/Avicia, m. Nigel de Plumpton).

Ralph's son Roger confirmed to Yedingham the grants of Helewise, Ralph and Mabel de Clere, his own grandmother. (fn. 25) Roger was stated in January 1249–50 to have sold and given away all his lands (including 5 carucates in Sinnington, 2 carucates in Edston, and the services from 2 carucates in Marton) except an oxgang in Sinnington. (fn. 26) These lands, however, descended to his heirs. http://www.british-history.ac.uk/vch/yorks/north/vol2/pp489-492

Roger Clerce III Herre av Sinnington

Han eide herregården i Sinnington, Yourshire og kan ha bodd der en tid, Han eide også eiendommer i Edston, Marton,

De ser ikke ut som han har hatt noen mannlige arvinger. Synes å ha hatt noen mannlige arvinger. Men sikkert en datter Agatha gift med William de Rus, og en annen (Amice/Avicia gift med Nigel de Plumpton. I januar 1249-1250 har Roger solgt og gitt bort alt sitt land (inkludert 5 carucates i Sinnington, 2 carucates i Edston og tjenestene fra 2 carucates i Marton) bortsett fra en oxgang i Sinnington som gikk til hans arvinger
