There are a number of female nobility who ( cousins, etc) are descendants or collinear relatives of the Romanov (Imperial) and lesser but still princely ( such as Gallitzin) families. I have reason to believe a Russian ( one would have to add ex-officio or in exile) Princess died fairly recently and at her funeral she had various Imperial Russian trappings including a Red Capelet over the top. She would be several generations down the hatch from Anastasia, of course. I seem to recall there is a Princess Catherine Romanov still living. She does not call herself Catherine III, by the way! so it goes.

Seeing as how their children would call their mother's grandfather, "Great Grandfather", I would think the husband could call him "Grandfather". Of course, there does need to be a mutual comfort level. Preferences about who calls who what can be clarified between the grandfather and the husband. The grandfather might prefer the husband address him by his first name, "Mr. Jones", or some other family moniker. Not all families have so many generations available to be faced with this kind of problem. Congratulations! By his name - either his first name if they are close, or Mr xxxxxxx if they are not close,
