#1 childfree bachelor

Ratan Tata is a Capricorn and therefore has not married and has no children. Capricorn is the sign of bachelors without children. 

 

Jared Leto has no children and a wife

Dima Bilan has no wife and children

Robert Shiehan has no wife and children

Everyone is a bachelor and has no children. All are Capricorns. Actors Orlando Bloom, Bradley Cooper and Sasha Golovin have no wife but have a daughter. Capricorns are very untrusting and categorical, relationships are impossible without trust. 

Nikola Tesla is Cancer, a bachelor with no children

Boris Korchevnikov is Cancer and he is a bachelor with no children.

We can find not so many Cancers among bachelors as among Capricorns, but there is  suspicion that Cancer is second after Capricorn.
