It was generally known, and reported by Miller, a long life friend of Lawrences, that Lawrence and Nancy argued considerably, whilst living on Corfu between 1935 and 1941. They living in Kalami, and the rest of the family elsewhere. It appears because of this that Lawrence spent a lot of time with his family, plus the fact that it was his idea to move to Corfu in the first place.
Lawrence and Nancy, now with child, left Corfu, fleeing the Nazi regime, and went to Egypt, where later in December 1943, Lawrence wrot to Miller and told him that he and Nancy had split up. They finally divorced in 1951, so that Lawrence could marry his second wife. Incidentally he married four time in total.
