Gwilym ap Jenkin, Master Sergeant of Abergavenny - Two daughters of Gwilym ap Jenkin with the same name

I was wondering if the two daughters of Gwilym ap Jenkin could in reality be the same person with two husbands? It seems a bit odd to have to daughters who have grown adults to have the same name. I have seen where a first child died very early and then have a second with the same name.
Any help would be very much appreciated.
Best,
John Love
