Is marriage to a deceased spouse's sibling an incestuous union to you?

She was (sort of) "your sister"? Far more traditional societies think she was sort of your wife in the first place.

And a lot of them actually made this a requirement, of course. Though more typically if she were to be widowed. Including the ancient Hebrews, of course, but the custom was exceedingly widespread the world over. It makes sense - if you assume a single woman can't survive. As traditional societies had to assume.

'kay, next question:

Is marriage to a spouse's deceased sibling an incestuous union to you? Or do you consider such a union bigamous? Or necrophiliac? Or none of the above?
