Hi, Steve

probably this Sioned ferch Cynfyn Fychan looks like a same as Jonet verch Cynfyn and need to be merged?

Sioned ferch Cynfyn Fychan ap Cynfyn ap Genillin, but same as Jonet ferch Cynfyn (Fychan ap Cynfyn ap Genellin), wife of Llewelyn ap Cynwrig shown here https://www.geni.com/documents/view?doc_id=6000000173392691854. Her ancestry shown here https://www.geni.com/documents/view?doc_id=6000000173393042912 (Jonet № 6)

both Llewelyn ap Cynwrig's (husbands of Jonet and Sioned) - may be same Llewelyn ap Cynwrig (https://www.geni.com/documents/view?doc_id=6000000173392691854) with long row of parent/grandparent etc with same names - all goes to common ancestor Ithel Ddu ab Ithel
