A step brother's cousin is no relation to you.
No, you share no ancestor with your cousin's stepbrother so you are not related. You could call that person your cousin if you were close or if he had been in the step-relationship from a very young age and was not asserting his different parentage.
There is no relationship, they share no common ancestor.
Certainly, you can date anyone you want, including your cousin. But your cousin's step-brother is not related to you, so questions of relationship do not arise. It's about equivalent to dating your cousin, so it's up to you if that's against your morals. As for genetics, having a child with him won't produce abnomalities if they don't share a biological parent with your cousin, but as for ethics, it's up to you. If the parents of your cousins step-brother are related to you no. But if they're not go for it!
First off, if your cousin and his "step-brother" have the same father, they are not step-brothers; they are half-brothers.Now, your cousin is your cousin (first cousin) because he or she is the child of a sibling of your parent. Perhaps your cousin's father married his sister-in-law after a death or divorce. If so, the cousin's half-brother is still your first cousin. Or perhaps your cousin's father married your aunt from the other side of the your family (a sister of your other parent). If the half-brother/step-brother is the child of your aunt, he is still your first cousin.In any case, it is OK to date your first cousin if you want to. The questions may arise in some, but not all groups and locations, if dating goes further and becomes sexual activity. Some jurisdictions and cultures find that to be improper; others do not.
Friends. You do not share a common ancestor. You are not related to your step dad, and you are not related to your brother-in-law.
Regardless of your living or guardianship arrangements - at most he is a step-cousin.
Your brother's cousin is also your cousin.
Im not sure what your asking, but they are stepbrothers. Candace is phineas full bro Hope I helped
The English language does not use the phrase "cousin brother." The brother of your cousin is also your cousin.
If you and your brother are both of the same blood, yes. Unless he's a step brother or something along those lines.
it is okay to date anyone who is not a "blood relative". Anyone who is a "Step..." anything is not a blood relative. For instance, it is okay to date your: Step Cousin, Step Second Cousin, Step Third Cousin, etc. it is even okay to date a step Brother or sister, however it is slightly looked down upon by most societies.
Your cousin's brother is also your cousin, but the cousin's wife is not related to you.
