If you are telling me I am wrong..and you have authority to know about this subject..I will go back and double check
It is my understanding that there had to be a legal marriage to get UK citizenship if born on US soil under the 1948 act.
Is your understanding different?

But it will take me looking over that and some other things which I no longer have the capacity for tonight.
Is your understanding different?
Hate to destroy that inflated ego of yours but I can't resist:
Children Bill [Lords], HC Deb 27 June 1958 vol 590 cc743-830:
"It is now the law that all persons born in the United Kingdom or its Colonies, or in countries which were Colonies at the time when they were born, have British nationality whether they are legitimate or illegitimate. . . .
****crickets********
"Under United Kingdom law as it has been since the British Nationality Act, 1948, the acquisition of another nationality by a citizen of the United Kingdom and Colonies, of whatever age, makes no difference whatever to his status as a citizen of the United Kingdom and Colonies, and, therefore, he remains a British subject.
Moreover, it is not possible, under United Kingdom law, for the nationality of a child who is a citizen of the United Kingdom and Colonies to be changed by the decision of his parents. Only the child, when he reaches the age of 21, can renounce his citizenship of the United Kingdom and Colonies if he is then in possession of another nationality, but during the child's minority neither the child nor his parents can do anything to forfeit his birthright of British nationality."

"It is now the law that all persons born in the United Kingdom or its Colonies, or in countries which were Colonies at the time when they were born, have British nationality whether they are legitimate or illegitimate. . . .
Also, it is part of our law that children of a British male born abroad can have British nationality."
I'm not trying to ruin your evening. But there is the cogent data that disputes your assertion.
