Translation of Scottish 16th century church stained glass

Question

This piece of stained glass (about 500mm x 400mm) is in our house but came from our adjoining castle. I think it came from a since ruined church on the same site. Anyone know what it means?

Answer 1

The heraldry makes play on ACRE (plough and barley brew) and HACKER (with the bladed instrument above the plough and the halberd). Such visual puns are called Canting Heraldry as the Heraldry Society explains. (Thanks! to TRiG)

The latinised name below the heraldry simply reads

Marci Ackerman (?Ackermani) : 1561

"Of Mark Ackerman : 1561"
The words are in the possessive case to indicate whose window (or whose castle, or room).
