I’m looking at the purchase in the mid-16th century (for “vs iijd”, which I read as five shillings and three pence, i.e. quite a lot) of “two aulter frontes of Dornyke and res.”

Any idea about Dornkye and res. (The full stop is part of the res. making it – is this right for the period? look like an abbreviation.)

All help gratefully received!
