Although I do know that my children are not the first generation to have CF, I just find the history of our family so interesting. Way back when, when little babies starved to death, possibly due to CF, sadly nursing moms usually took the brunt of the blame. I find it amazing that you can go back for many generations like Liza, and find no indication of CF on either side of the family. My parents have not themselves been tested to see which one carries the gene, and have always suspected that it was my mom because of her brother that died of the spastic colon at 2. But one of my cousins on my dads side is a known CF carrier. Sometimes I wonder if both parents carry the gene and my sister and I just got 'lucky' and didn't get both. Who knows, but I do find genetics very interesting (although I do wish my children and nephew didn't have CF of course!).
