I haven't done any research on how widow's peaks are passed, but genetics can reach back a long way! Even 4 generations! So -when you think about all of those grandparents and great -greats on both of your sides, there's probably a widow's peak somewhere -even if what you read said it didn't skip generations. There are also anomalies. A little girl who used to be in my first son's playgroup had dwarfism, and they were told it was genetic, but NO ONE on either side of the family knows of anyone with dwarfism or ever heard of anyone with dwarfism. You also have to take into account -that especially a long time ago -who we *think* is our great-grandfather -well -maybe that's not who is really our great-grandfather! One of my paternal great-grandmothers was at least 1/4 African American -if not half. I have her photograph, and you're just not convincing me or some other members of my family otherwise! She supposedly had a lot of "Cherokee" blood in her. Hmmmm -yeah -right. That's quite common, particularly for families who have lived in the South for hundreds of years. So -who knows! It could open up a whole interesting ancestral search for you!
