If you are a manager of a profile I tagged, you're more than welcome to join this project. Anyone who would be able to create profiles for the people who are missing, your effort would be greatly appreciated as this is an exceptionally rare eye condition, so the more help the better. Having as many people in this project who have heterochromia as possible could potentially really aid in tracing a commonality between the people themselves through their genetics, family in common, etc.

I will simply start out by stating that this condition is exceptionally rare. I grew up thinking my eyes were just brown and my mom's were hazel. I have hazel eyes and she had blue, only she had yellow in hers and I had both green and amber/brown, plus bluish edges which typically fade in older ages. I'm very intrigued to find out the what/when/who/where/why of this blue-eyed ancestor. It may surprise people or simply be nothing incredible at all, but I have a hard time with that one. I'm also curious if the introduction of someone's DNA spurred eye color mutations or if it happened on its own and also if the blue-eyed common ancestor was the reason heterochromia is even a thing. I do know that some people in ancient times were said to have had one "black" eye and one blue and that it was referred to as having the "evil eye". In animals, the lack of diversity when creating offspring is believed to have caused it, which would stand to reason that producing children with closer relatives could have led to this condition. Really shocked there, right? Not! Ha!! 

I researched heterochromia to find out that my mom had sectoral and then saw that I actually have central heterochromia. My minimal research has shown that less than 1/2% of the global population has heterochromia of any capacity, full or partial. What my research also showed me is that there are a list of syndromes and diseases associated with it and that it can be either inherited or caused, perhaps, by head traumas. I had a substantial amount of head trauma in my life since early childhood, but this condition is definitely inherited. I have no doubt about that. I lost where that link was, but none of that seemed to fit me or my mom. There's also a list of other medical conditions accessible via a link at the bottom of the heterochromia Wiki page. I'm not a doctor, so I'm going to leave that alone.
This does lean into the conversation about a shared blue-eyed common ancestor. Very recently, I became aware of a very interesting story about the birth of Noah, I believe from his father's perspective, from the Book of Enoch. Lamesh described having seen "sons of God" and made reference to "brightness" in those beings. At birth, Noah was described as being having pale skin with pale hair, and eyes so bright that the light filled the room. Regardless of peanut gallery commentary, people do descend from ancients, whether we can prove it, or not, and this story is particularly interesting to people who believe that they descend from Noah.

Then there's Cheddar Man, who was found in Somerset, England, a place very inhabited by my family since at least his time. I'm a DNA match to him and he may possibly be related to or have associated with people during the active times of Stonehenge and/or its construction. Obviously, data is limited on many people, places and things, so we clearly lack definitive answers. We have to presume some information has been concealed, while other things lost over time. I personally don't know of any other blue-eyed ancients anywhere near Cheddar Man's location or period of life, nor do I have any data on any other ancient person on the subject of eye color. My thoughts are simply that there is a true connection to all people ever who have had ancestry of people with eye color lighter than simply straight brown. This blue-eyed common ancestor, if it were indeed just one contributor, would have been a regional contributor and thus logically also provided a shared ethnic ancestry, possibly even less than by country, but by clans/tribes within countries which had multiples of either or both throughout different historical eras.

Wikipedia says, "it can be inherited, or caused by genetic mosaicism, chimerism, disease or injury. It is quite incredible to be learning of this. I knew I was rare, but that's pretty darn rare, exceptionally rare when my height is taken into consideration as I am 6'8" or 203cm. I have found out I am Basque for sure, but also knew I am Faroese. Both seem pretty darn rare as well. Manx from Isle of Man may be kind of up there as well. Iberian is one also, which I thought was Basque but you can be Iberian and not Basque, from what I have ascertained in research on the subject. What does this mean? I do not know, but I think this is a highly intriguing project to have on the web, on Geni and on our radar so that we can begin to pinpoint more of these ridiculously miniscule traits potentially to a source. Stranger things have happened, they really have. ;-)

There are a handful of notables on this Wiki page said to have had it, half of which I know are bio family already. Then there is another page I'll include with other notables. The ones I recognize were almost all already confirmed as bio family. Hopefully this does gain some attention. I find it highly fascinating, especially because it is more common in animals than it is in human types of animals. Ha! That's definitely worth the research and definitely worth having a project for. I don't know what it means, but I'm not afraid of what it can lead to being discovered. I am a truth seeker and that's what I aim to do. Thank you to all who choose to participate without judgment.
