In some version of a sequel or perhaps a draft, or even Weingertner, there was something to the effect that Connie and Merle did marry and they got on some fancy ocean liner. Michael found out and cut her line of credit and they were thrown off the boat and brought back to the US on some really crappy liner. After that Merle saw he wasn't going to get money out of Connie and he disappeared.
I think that was from "Godfather Returns."
Wouldn't it have been something if Michael had Merle whacked? Then he would have killed
two of his sister's husbands.
