According to the last written record pertaining to Greenland, a couple was married at Hvalsey Church in Greenland, and this couple later relocated to Iceland. Is it possible the remainder of these people also left Greenland, if not in one big wave, then over the course of several decades?
hi! new info would be welcome on this question, but until now the answer seems to be "we don't know"
edit: oh, just stumbled into this one from a couple of days ago
