If a mod decides it should be moved, that’s OK with me if I can still find it.
I have a question about certain kinship terms under specific circumstances which I shall explain.
The questions, which won’t in my opinion make sense without the background I’ll provide after the questions, are:
I have a far-future interstellar multi species conculture whose founding core or kernel or nucleus is an all-human conculture with a particular kind of classificatory kinship system.
In this system:
In both the earlier, all-human, conculture, and also the later, multi species, conculture, humans are expected, ideally and circumstances permitting, to marry three times.
* The first time to an older member of the same species opposite sex who has already married once and already had at least one child but is still capable of having at least one more;
* The second time to a younger member of the same species opposite sex who ideally has never been married and ideally never had a child but is able to have a child;
* And the third time to someone, traditionally close to one’s age.
Ideally and traditionally and usually, if one is human, both of one’s first two marriages produce offspring, but one expects no offspring from the third marriage.
As interstellarization proceeds, third marriages are taken to be for companionship, or other reasons having nothing to do with reproduction. Eventually this leads to looser restrictions about who can marry whom. Age differences can be greater; one’s third spouse can be a different species; one’s third spouse can be artificial instead of biological; one’s third spouse can be more closely related than would be permitted for a reproductive marriage; and one’s third spouse can be one’s own sex.

So here are my guesses, but I’d like to hear yours.
One’s father’s husband is another father, just as one’s mother’s husband is.
One’s mother’s wife is another mother, just as one’s father’s wife is.
A man’s brother’s husband is his husband;
and a person’s husband’s brother is their husband.
A woman’s sister’s wife is her wife;
and a person’s wife’s sister is their wife.
A person’s husband’s husband is their brother.
A person’s wife’s wife is their sister.
For at least this post I’m not going to worry about how species affects kinterms.
