First Windows Phone 7 Genealogy App

Saturday, 25 Sep 2010 | by Mark Tucker

I am excited to announce what might be the very first genealogy app for the soon-to-be released Windows Phone 7.

It is a graphical cousin calculator that can determine the relationship between two individuals by knowing the relationship of each to their closest common ancestor.

With just a few taps and drags, you can determine the relationship of any two people.



The application is in final development.  Please provide feedback.

  3. Dear Mark, All the relationships you mention are of the half blood. You mention brothers and sisters, but you say they descend from a parent. You mention first cousins and say they descend from a grandparent.

    You need a couple to have the relationships you mention. I have been trying for years to get this straightened out on the internet where copiers are at work copying that wonderful cousin graph over and over.

    So how about a cousin whom you share only a grandfather with. That would be a half-first cousin. If one would think of an grand parental COUPLE instead of a single ancestor, that would correct the situation. YOu might argue that going way back it doesn’t matter by much, reducing the ancestral connection by 1/2 of a very little bit. But in genetic counseling where half siblings mean a great deal, compared to full siblings, it is a dreadful mistake.

    Yours truly,

  4. Thomas,

    I appreciate your feedback. Let me make sure that I understand what you are saying. In order for it to be a full cousin relationship both people being compared must be related by a most common ancestral couple. So in order for the cousin calculator to be accurate, it must show a couple at the top and not an individual. If two people are related to a common ancestor but not the same couple, then it is a half relationship. In order for it to be a full relationship, they would need to go up another generation to the parents of that common ancestor. Every half relationship can be changed into a full relationship by going back one more generation.

  5. I just wanted to direct you to this blogpost

    It’s just funny because I’m not a genealogist, amateur or otherwise, but I ran into both these posts on the same day.

    Nice blog Mark.

  7. I just bought my android phone – I hope they will make this available for it or my iPhone. I haven’t done much genealogy for the past couple of years but am getting back into it.
