A chronic mental disorder usually contracted in mid and late adulthood, though occasionally found in teenagers. Disorder is characterized by a strong desire to conclusively identify every member of a family. Sufferers enjoy reading obituary columns and frequent trips to cemeteries. Physical symptoms include: an involuntary twitch when the word “ahnentafel” is mentioned in casual conversation, dilated pupils and increased heart rate when passing local libraries or state archives, sweaty palms in the presence of a microfiche. Only known cure is death, which must be proven with the appropriate certificate. Copyright (C) JMK Genealogy Gifts.
