St Andrews Cheddar - heraldry

[Jeremy Pyne]

I'd be very interested in advice on possible sources to both identify and explain the context of heraldic shields included in what I understand maybe 15th century stained glass in St Andrews Church, Cheddar. The family arms for the Pyne family - primarily a Devon family are included, along with some others which are less easy to identify. I've so far not come up with much by way of church histories or research into these windows. Nothing jumping out from the Somerset Archives on line catalogue. I would have thought someone will have in the past looked to understand the heraldic references here. While having a lot of background and records on the Pyne family in the wider South West, I've not come across early connections with Cheddar, so would be really interesting to uncover some new links.
