More than emotions, it was that their lives were being affected in some form: something else was being added to it that was not there when they decided to enter into a relationship. Particularly for the mother, she basically entered into a relationship without all the facts known. Maybe she would have decided differently at the beginning.
Personally, I am not sure why the sister is so upset. It's just another sibling, which should bring happiness. But in a world where lawsuits are common, maybe she also feels threatened (sharing of inheritance, for example?).
I think it is fair that the mother is upset. She has to deal with more "baggage." But I don't think this is worth divorcing over. Things must not have been that solid for this to end up in divorce. A strong marriage should have survived this.
It's probably not a good idea to speculate on the relative strength of other people's marriages, especially internet speculation. We still don't know everything that happened; nor should we. So, let's not pretend that we know what is going on here.
The basis of the story is that with genetic testing with a service like 23andMe you can find things that you may not have wanted to have known or expected. Let's just leave it at that.

Absolutely. When we make bold assertions like "X would Y" we are bringing a huge amount of personal bias, baggage and most of all ignorance to the table. It blinkers us to the vast range of possible realities that our impoverished imaginations (and our imaginations are always impoverished) are incapable of conjuring.
As an exercise, before posting "X must be Y" it is very much worth-while thinking of half-a-dozen movie scripts that could tell a story that would fit the known facts. In the present case they might look like:
1) Basil Fawlty-like character goes off the deep end upon discovering child from before his marriage
2) Uptight wife divorces husband for youthful indiscretion
3) Husband's former double-life as a spy revealed by accident of genetic testing
4) Husband's former criminal life revealed by accident of genetic testing
5) Christian wife divorces when accident of genetic testing reveals husband was not a virgin at marriage as he had always claimed
6) Radical feminist wife leaves husband when she finds out he once patronized--and impregnated--a prostitute...
The only thing we can say with any degree of certainty is that the reality is far weirder than anything we can imagine. It almost always is.
In none of the above cases would the marriage necessarily be describe as "not strong" prior to being put to the test.
To claim that "a strong marriage should have survived this" is vacuous tautology: http://www.tjradcliffe.com/?p=1087. It is true that a marriage strong enough to survive whatever happened would have survived whatever happened. It is also true that a big enough blow will disrupt anything weak enough to be disrupted by that blow (http://www.cuug.ab.ca/~branderr/risk_essay/hymn_strain.html)
True, you can't be exactly sure based on a single case. This might or might not have been a strong marriage. Even very strong marriages sometimes but rarely break up out of nowhere.
But the initial statement is true in a probabilistic sense. A strong marriage most of the time will survive learning about this kind of event that happened well before the marriage started. That the marriage didn't survive is not conclusive, but does suggest that it was probably not a strong marriage.
I don't see any problem with that, as long as there is a clear distinction made between what is known and what is weak likely conjecture (and it's anonymous).
