"(Prohibition of marriage between relative by blood)
Article 734. No marriage may be effected between lineal relatives by blood, nor between collateral relatives by blood up to the third degree of relationship; however, this shall not apply between an adopted child and any of the collateral relatives by blood on the side of the adoptive relatives.
2. The provision of the preceding paragraph shall also apply even after the relationship has terminated in accordance with the provision of Article 817-9."
Yes, since they aren't related to you by blood.
