I'm creole on my paternal side and an aunt of mine married into the Glapions who are descendants of Laveau. I personally know some of the Glapions and they are extremely wealthy and successful so I wonder if there is something to that but I don't know them, at least the ones that I know, to be people who have carried on in being practiioners or even superstitious.
Not sure about the nature of this question.
Whatever your faith is, go talk to the professionals-lol i.e. a priest or minister.
I come from a religious family but I'm more agnostic these days. However, I do have a foundational understanding of Christianity (I descend from a bishop of a church and have many priest in my family with divinity school credentials from places like Yale/Harvard).
There is a certainly an understanding of curses within Christianity. For instance "Cursed is the ground that you will walk on..." or "I will visit the sins of the father.....". However, these were instituted by humans because of their own actions and because they turned away from God. These, however, are void for those under the blood covenant of Christ. Additonally, if one is a true Christian, spells and curses that have originated from other people have
no impact on them.
"...having canceled the debt ascribed to us in the decrees that stood against us. He took it away, nailing it to the cross! 15And having disarmed the rulers and authorities, He made a public spectacle of them, triumphing over them by the cross.16Therefore let no one judge you by what you eat or drink, or with regard to a festival, a New Moon, or a Sabbath.…" Colossians 2:15
We know that whosoever is born of God sinneth not; but he that is begotten of God keepeth himself, and that wicked one toucheth him not. - 1 John 5:18
Again, the understanding is that Christians are the physical body of Christ whom "disarmed the rulers and authorities". There is nothing on this earth, or under this earth, or above this earth that has dominion over that body. Additionally, instead of partaking in paganistic rituals to rid demons, like Christ, true Christians, with the power of the Holy Spirit, can simply call and cast them out (there is no florida water needed for that-lol). With that being said, if you're not covered under that blood covenant, and open up yourself to certain things (ie mediums, divination, witchcraft, etc..) you open the doors for things to happen. If your'e concerned, you should talk to a priest/minister. There is a lot in terms of spiritual warfare going on these days and you have to be strong spirtually to withstand it.
