Bydd Aelodau'r Cynulliad yn cofio Syr Ronald yn cael ei benodi gan Ysgrifennydd Gwladol Cymru ym 1996 i gadeirio Tribiwnlys Ymchwiliad Cam-drin Plant Gogledd Cymru. Wrth edrych ar y dystiolaeth o achosion o gam-drin plant mewn gofal ar draws cyn-siroedd Clwyd a Gwynedd ers 1974, gwrandawodd y Tribiwnlys ar dystiolaeth gan 575 o dystion rhwng mis Chwefror 1997 a mis Mawrth 1998.
Assembly Members will recall that Sir Ronald was appointed by the Secretary of State for Wales in 1996 to chair the Tribunal of Inquiry into Child Abuse in North Wales.  In examining evidence of widespread abuse of children in care in the former counties of Clwyd and Gwynedd since 1974, the Tribunal heard the evidence of 575 witnesses between February 1997 and March 1998.
