Two people who have at least one grandparent in common are first cousins. Your son and your stepbrother's son may be first cousins, or may be unrelated. Even if they are unrelated that can call each other first cousins if they get on well together and want to do that.
Great uncle / Great nephew
No because that would be your cousin
Step-brothers
Your grandson is the great-nephew of your brother.
Yes, she did. She had the relationship of a mother that a mother has with her son. As most mothers do.
Your younger brother's wife's sister's daughter would be your son's cousin.
i suppose so. if your a redneck...cousins are free game
Your brother would be your son's daughter's great uncle and your son's daughter would be your brothers great niece! Hopefully that makes sense :)
The relationship of a stepbrother's son to someone would be that of a step-nephew. This is because the stepbrother is not biologically related to the person, but is a relative through marriage. Therefore, the stepbrother's son would be the person's step-nephew, as they are the child of the stepbrother.
If her son is from a previous relationship, then he would be your step-son.
a relationship between brothers should be sacred and good....
A father and son relationship is called a paternal relationship.
