After wondering about the four people with alopecia over several generations in my family tree, I have been missing the obvious option to trace this: AlopeciaWorld! If anyone can tell me the present and past (1800s and earlier) prevalence if AA, AT, and AU in Wierzchoslawice, Poland (particularly in the Bogusz families), please let me know! I am also about to do the Ancestry.com DNA test...but I hear there is a DNA test with another company that focuses on males. Out of those I know since great-grandpa brought it over from Poland with him (his toupee was found in the family safe in the 1940s), I am the only female with alopecia in our USA branch of the family.
