If you have 2 brothers whose names start with M and P, and your mother's name is Magdeline, you are indeed my 2nd cousin and we share grandparents. I met you once a long time ago when y'all visited us in Florida. I knew your father Karl from when I was six years old. He was a lot like my grosspapa Fiala.
