Hi Mandy and Fireweaver.
Yes, it is quite archaic how all of these children born to royal mothers cannot have titles bestowed upon them unless their father is granted a title or their father is royal. The male lineage is most important and the most significant factor in one's being considered royal.

It is really becoming quite boring. It's not as if one's mother doesn't play a significant part in one's conception, development, and birth. But, I guess that is only biology and as usual in some instances men are given much more credit and consideration than they deserve.

Unfortunately, this has and is the traditon in most or all royal houses. It is very archaic IMO, but I doubt that will change anytime soon unless monarchs take it upon themselves to bestow titles upon some or all of these children.
I agree that something had better be done about the shortage of royals in some countries, especially in Norway as there is a major shortage and the referendum as Mandy mentioned will be approaching soon enough.

Good point Mandy-the fact that ML and Ari will be moving to NY with their child doesn't make this much better.
However, I do wonder when considering ML's move to New York and the fact that she requested her HRH be dropped if she really wanted her children to have titles at all? She and Ari may be doing as The Princess Royal of GB and her first husband, Mark Phillips did with their children in refusing all titles.
