What is considered acceptable in family relationships?

My brother has been married twice. The first wife died as a result of an auto accident. He now has a large family three children from the first and two from the second. Three of the kids are now in college. He just found out that his oldest girl is pregnant and the the father is a son from the second marriage making the relationship stepbrother/sister. I know cousin relationships are acceptable but this does not sound good to me. My brother has asked me for advice and I don't know where to start. What is considered acceptable in family relationships?
Tell em to get the abortion. baby could be bad who knows two heads. you aint supposed to do half sister. make em use condoms too until they break up. What is considered acceptable in family relationships?
sounds more like a half brother than a step brother if the son and daughter are his biological kids. In most family's even a marrying step-sibiling is a little frowned upon, but if both of his kids are biologically his but share a diff mother, then this is technically a case of incest. Unless your brother has the most liberal family in the world, your family and many others aren't going to accept it. Even when first-cousins have had children together, there's a high risk that the child will have mental or physical defects, or both, so i hope your niece and nephew know what risk they've just taken and i hope that somehow this won't be too embarrassing for your family.
Well, they are not blood related so technically there is nothing wrong with it. I guess where it looks really bad is if they grew up together as kids. For instance, my brother married a girl that has a daughter that has a daughter that is 9 and my nephew is 8.. now if later on the decide to have a relationship, that would be a little strange to us because they grew up together as children. In my family we have something similar. My uncle married a lady that had a daughter from a previous marriage.. and my uncle's brother married his ';step'; mother's daughter. It sounds weird to explain but there is nothing wrong with it.. they are not blood related.
That is still incest. They are family from marriage or union of their parents. Your brother should have them see a psychiatrist and hopefully they can see what they did wrong and what is wrong with the relationships. Even-though the baby will not suffer from the relationship physically it will have to deal with the fact that his or her mother and father were step brother and step sister. That kid will be messed up
Firstly to whoever said 1st cousin relationships were illegal, you are wrong. They are perfectly legal.





Anyway, as far as step brother and sister go, they are not related by blood, so it is fine. If they have grown up together as a ';brother and sister'; since a young age, then it may be questioned by social services. Otherwise, it's just some extra paper work I believe? (For marriage anyway)
Wouldn't it be half brother and sister? Isn't he the dad of both the daughter and son or were the two kids from his second wife from a different dad? If that's the case, he'd be dealing with incest...right? If not and they aren't related at all...it isn't as big of a deal. Still weird, don't get me wrong but none of this is his fault. They are the ones that are going to have to face society and explain to all the people that look at them and question why they would do it.
I take it his second wife already had two children before they were married, otherwise they would be half-brother/sister not step. That could have serious medical issues associated with it. If it's against the law, children's protective services could get involved. If it is an issue of incest, he should take his daughter to a genetic specialist.
Wait is the son from the second marriage his child? Or from another father? If it is from another father, then its ok, just kind of awkward, if its his actual son and they are half brother and sister, then good grief and good luck with that.i think there was a song by ray stevens like that, im my own grandpa.
wow so much is wrong with that entire situation...its not a stepbrother sister ..its a half brother half sister ...if they share one of their parents and the way you have written it they do..it happens mainly to mountain people in ky wva and nc...its never a good thing there are alot of health issues that come from inbreeding...the best advice at this point is for him to talk to a pastor or counselor...if it is a step sibling and his child..meaning he isnt the father of one of them...its not a big deal they are not truly related..will be a bit weird but its a doable situation...many people meet the people they marry through family and thats all that would truly be..i hope they are both of age...he can stay out of the situation and let them figure out what they are going to do..good luck
Is he a half brother or step brother? Is your brother the father of both these children? If so the child will be inbred and will likely have all sorts of problems. If not the child will be fine.





Cousin relationships are also not acceptable.





Edit: To those saying first cousins can legally marry, it's illegal in 25 states.
It not really wrong since there step but if they were half brother and sister then that could be wrong, but it not wrong but to me it not right but if they love each other then there is nothing they can do, and just let them do what ever but to me what done is done can change that. so I would say your just going to have to deal with it in your own way.
Do they have the same father? If so, this is incest, and a bad idea. Mixing so close in the gene pool is never good.





They won't be able to get married for starters because it will be illegal.





If they aren't related by anymeans...it's a very weird situation but shouldn't cause a problem.



Step siblings are not blood related, so there is no issue other than perhaps some awkwardness related to them being raised together (if they were).





Cousins are legal and they are blood related, but often not raised together so there is an environmental difference in the two situaitons as well as a family one.
There is no blood relationship, therefore no harm to the baby.


It does sound different, but they may truly be in love. Whatever the situation, I hope you agree she needs support.
Cousins in relationships are NOT acceptable. Stepbrother/ sister is not acceptable IMO. Tell him it is disgusting if that is what you think.
No matter how you look at that, it's wrong. They are for all intent and purposes, brother and sister. Weren't they raised as brother and sister?
They're not blood related but it is still very odd. I can't understand how someone could find a stepbrother or sister attractive. If the new wife has not adopted this girl, they're not really considered brother and sister.
No blood relationship. As if strangers except they are step children to each other.


Weird but not unworkable.
Doesn't matter if it sounds good to you..Its already happened. They are just going to have to deal with it..so keep your judgemental stares to yoursef.
First cousin relationships aren't acceptable. Too close genetically
Ever seen the movie Lonestar state of Mind? Same thing hahahah it's all good
Um they share there fathers DNA that child might end up with medical problems. Not good
Sweet Jesus !!!!!!!! Definitely not this.





Where do you live West Virginia ?
thats kinda messed up if you ask me
thats not good. first cousins are to close. their could be some health problems.
