Wish I had been able to learn about such stuff as conjoined genitives, case-marked genitives, cataphoric, anaphoric, and right and left branching. A hundred years ago we prescriptive grammarians spoke of joint and individual possession. Joint was "America and England's problem," and individual was "America's and England's problems." I reckon we Miniver Cheevys would just have said, re the example at hand, "my wife and my grief."
