It is not okay to date your half niece. You are still in some way blood related and if you ever were to have a child together, it may be subject to deformities.
The site stripped the parentheses from the question. It should read: "What is the technical term for the familial relationship you'd have with your half-niece's (daughter of half-brother) son?" Your half-niece is your half-sibling's daughter. So what is the term for your half-niece's daughter, in relation to you? My first best guess would be "half-grandniece", but that doesn't sound right to me, and I guess it with absolutely zero authority. Hopefully someone can give the correct answer.
A half-niece and her uncle are expected to share about 12.5 of their DNA.
Your niece.
Your half-brother's daughter is your niece. Your niece and your son are first cousins to each other.
Technically, the baby would be your half-niece or half-nephew, and you would be their half-uncle or half-aunt. But many people dislike the term half or step (I have two stepsons and one natural son) and only for official purposes would I use the term half or step. So I'm with C3 Shooter on this, treat them as your nephew or niece.
Totally not classy! unless you are sure both of you cant afford it. Have them pay for half, (go dutch)
in my opinion, i dont really think so...
It would be perfectly fine to give your niece a summer dress as a present, many companies that sell them can be found via the internet and there is a wide variety.
Yes it is. Unless you're talking about going further, and one is eighteen and the other isn't. That's a no.
In terms of genealogical relationships, a great niece is the child of one's niece or nephew, while a half great uncle is the half-brother of one's grandparent. Legally and socially, marriage between a great niece and a half great uncle would not be prohibited in most jurisdictions, as they are not closely related by blood. However, such a relationship may still be viewed as controversial or unconventional due to the significant age gap and familial ties.
That depends on the situation. Your brother's sister-in-law could be your wife or the wife of one of your other siblings. As long as the sister-in-law is not married, there is no reason you can't.
Its ok to date a handicapped.No the ideas will not interfere with your relationship.
