I am shocked by your grandmum's boldness especially in 1940.....during ww2 my grand mom who was pale white skinned and living in britian , took a black lover while my grand ******* was overseas fighting the germans, and this was in 1940 the black man was some thing in supply so was not away fighting, he managed to spunk two mixed race babys in to my grand mom and as she lived in a cottage in the country she had both babys my grand ******* came home and excepted the babys and raised them too, she had my mom after the war
