MCMXCV, I suggest that you you take the component values from your family kits and arrange them the way I did for your K13. What you need to do is copy the values from the page
before you click "oracle" on the GEDmatch site. So, copy all of the values in that exact order, even the zero's. Then write them like I did for your K13, or for example: Grandparent1,32.59,32.48, but include all 13 values, or in the case of K15, all 15 values. Then start plugging them into the calculators here:
