Marriage within extended family members, is that a feasible act?

Dear Writer,
Thank you for contacting the askmile team with your interest and love for your maternal cousin whom you want to marry. It is very painful if someone comes with the view that you cannot marry you love. It would break both of your hearts.
There are many different types of customs and practices regarding the various groups and sub-groups in this country. In some quarters cross cousin marriages are not permitted while in some others it is encouraged. You have not seen any marriage in your family or community with maternal cousin. This makes you think it is not permitted. It is better to find out what would happen if you propose to marry her and share this with your parents and the church? Please find out what would happen if you marry maternal cousin?
