Hi Mrs Wheeler but my name if Godfrey Buquet, not Dulac. You inquired, I think, about Dulac Plantation. It was once owned by my great-uncle, Aubin Buquet (deceased). Prior to his ownership, I believe it was owned by Mr. Ellis Lottinger (deceased).
BTW, Dulac is not really a surname, as far as I know, it is French for "The lake" or "Of the lake" The word "Du" in addition to "The, of the, some" has additional meaning in French, but in this case Dulac is a small village where a good portion of the population is American Indian. The name Dulac, I believe came about because the land where the plantation was is bordered by a lake; Lake Boudreaux, actually, but I think the plantation got it's name before the lake got its name.
Your husband's dream is quite weird. Regardless there is no Godfrey Dulac.
Have a good day, and Happy Easter.
