Can two blood brothers marry two blood sisters from the same biological family
Is not allow in any yoruba culture, and by the way why is it that u want to marry from the same family with ur brother when there are lot of ladies in this country which u can propose to.
from my own point of view is not a good idea cos (1) there will be no respect btw the two sisters
2. is never done
3. i believe is forbidding
4. it may create controversy in the family
