My Cousin, the Pope

I'm Jewish. I married a Jew. Both of my parents were Jewish. And so on. And yet, apparently, I am the cousin of a Pope - specifically, the still-living but now-retired Pope Benedict XVI. In fact, Pope Benedict XVI and I descend from at least two common ancestral lines.

The first is via our mutual great grandfather, Abraham Zwillinger, who was born circa 1754 and tracing down from whom, Pope Benedict XVI and I are fifth cousins, once removed.
