A manuscript which narrates the descents of the founders of Lanthony Abbey names “Rogerus primus comes Marchiæ” as son of “Edmundus de Mortuomari”. A manuscript narrating the foundation of Wigmore Abbey names “Rogerum primum comitem” as son of “Edmundus de Mortuomari…Rogeri de Mortuomari…secundogenitus” and his wife “Margaretam…filiam domini Willielmi de Fendles de Hispania”.
He succeeded his father in 1304 as Lord Mortimer. He took possession of Meath in Ireland, inherited from his wife, 28 Oct 1308. He was appointed the king's lieutenant in Ireland 23 Nov 1316 and crossed to Ireland from Haverfordwest with a great army in Feb 1317.

He escaped 1 Aug 1324 and fled to France where he became the lover of Queen Isabelle, who went there in the spring 1325, and together they landed near Ipswich 24 Sep 1326 where they were joined by other opponents of the Despencers who were captured and executed.
He was created Earl of March [25/31] Oct 1328. King Edward III led a conspiracy to rid himself of Mortimer who was captured at Nottingham Castle 18 Oct 1330, condemned to death and his lands forfeited.
