Did your home float away during Katrina? Have you ever met a black Cajun? I bet that would be odd. A black Cajun is probably like a black Jew.
The water came up about half way up our lawn, so we were in no danger. In fact when we returned 4 (or was it 6) weeks later the ice cubes hadn't even totally melted in the freezer. I'm guessing we were without power for maybe 36 to 48 hours.
No, I've never met a black Cajun. The Cajuns are the French expelled from Canada when the English took it over. There are Cajuns (Acadiens) in the Northeast and in Southern Louisiana. They didn't own many, if any black slaves since they were pretty impoverished, so a black Cajun would be a rarity.
As far as black Jews, yes there are the Ethiopians. In fact there was an isolated community of Chinese Jews who were "discovered" by the Catholic priests many, many years ago. Since China was an isolated country, they thought they were the only Jews left in the world.
And anticipating your next question, yes I did have ancestors who owned slaves. My Irish GGGrandfather immigrated and within 10 years he owned 2 female adult slaves and a four year old boy. I don't know if the boy is his because researching the slave sale records is tedious. Other things have crept into my life, but I intend to hopefully find out more information.
