Welcome! :) This project has 3 aims. Aim 1.) comparing the Y-DNA of people with the surname 'Kogel', or variants thereof, in order to establish if they all descent from a common founder, or if there are multiple founders of this surname. Since 'Kogel' is a very rare surname, however present in many countries (USA > 12x, Germany > 2x, Sweden > 1x, UK > 2x, the Netherlands > 6x, Belgium > 2x, Costa Rica > 7x, Spain > 1x), it is likely that there was a single founder several 100's of years ago, whose descendants were then forced to leave the original country in which the person lived, who first carried the family name 'Kogel.' Aim 2.) anyone who matches either the Y-chromosome of my patrilinear line of descent (= Schweitzer = E-V22 [E1b1b1a3]), or any of my mitochondrial results (J2 & T2), or any of my research samples (Y-DNA = J1, E-V13, I2a, L, O & mt-DNA = B, H) is also very welcome to join. :) Aim 3.) anyone who is just interested in expanding his/her knowledge about his/her descent is also very welcome to join this project. :) Notice: All Administrators of FT-DNA Projects are Volunteers and receive no Compensation or Incentives from Family Tree DNA.
