Whakaotihia te rerenga e whai ake nei: I whanau a Thomas Dudley ki Yardley Hastings, he kainga tata ki Northampton, Ingarangi, i te 12 o Oketopa 1576, ki a Roger raua ko Susanna (Thorne) Dudley. Kua roa te whanau e kii ana i nga hononga ki nga Sutton-Dudleys o Dudley Castle (Duke o Northumberland, Earls of Warwick me Leicester, Viscounts Lisle, me Barons Dudley); he rite tonu o raatau kakahu, engari ko te hononga i tua atu o te tupuna noa kaore ano kia tino whakaatuhia. I mate a Roger Dudley, he rangatira i te ope Ingarihi, i te pakanga. I whakaarotia mō tētahi wā i whakamatea ia i te tau 1590
Ko te Pakanga o Ivry, engari ko Susanna Dudley e mohiotia ana kua waiho hei pouaru i te 1588. Ko te pakanga o Zutphen i te tau 1586 kua whakaarohia hoki ko te take o te matenga o Roger Dudley.
