Thanks. But the point is that these examples are from one and the same list of characters and I'm trying to feel the difference ))
It's good to know that these are from a list of characters (in a play, I assume -
Amadeus?), but it is strange that they would use two different constructions, since the meanings are really the same. Also, as
emsr2d2 posted, both
wife to and
wife of are seen most often in obituaries or character lists like yours (although
of is sometimes used in writing or conversation).
In terms of
feeling the difference, my feeling about "wife
to" is that it is more formal or impersonal - like the arrangement was mainly for convenience. (But if the list you're referring to is from
Amadeus, then this feeling isn't true to the characters, so then I have to say that I don't know what the difference is!)
I think the final point is that
to would never be used in daily conversation or writing, and it means the same as
of in this case.
