The Moroccan/Indian thing isn't that impossible, Shagman45.
Until just a couple of years ago, London's huge Moroccan population was the largest, outside of Morocco, except for Paris and Marseilles. A few more French cities have now caught up but London is still a big Moroccan city. Anyone, who knows the Portobello Road/Golborne Road markets and neighbourhoods, will know that. Grenfell Tower was full of Moroccans, as is that estate and neighbourhood. The W10, W11, W6 neighbourhoods are full of them. They were highlighted (Golborne Road Mosque) as a hotbed for young terrorists but that's gone quiet. They're into fourth generations, now.
There have been loads of mixed marriages and mixed shagging (usually Moroccan guys with Spanish, Portuguese, British girls) so don't discount anything. If a Moroccan girl gets pregnant, outside of marriage, chances are that she's slung out on her ear and ostracised, so any offspring won't be brought up as a 'true Moroccan'. Might well go into prostitution.
