Hi
You're right both ways because Peter married Catherine who was the widow of a Huddleston and the daughter of a Corrin. If you can get my website to open (which I cannot at present) you can see her family properties at 07/01, 07/08 for the Huddlestons and 12/04 for the Corrins. www.manxroots.com
If you are interested in Peter's lineage he was a younger son of Thomas MHK of Ballakoig, Ballaugh. His brother Ewan Corlet was probably living with Peter at the time of the Douglas 1730 Census as Peter is there but Ewan not named. I descend from Ewan.
