Patton Cobblepot was responsible for building out Gotham's subway system before the turn of the century.

Patton's youngest son, Barnabas Cobblepot was a famous occultist and hypnotist, who joined The Victorian Legion and endowed a professorship of psychology at Gotham University. Barnabas mysteriously disappeared during the the_great_gotham_fire_of_1911.

Barnabas's nephew Desmond Cobblepot is the,current head of Cobblepot Amalgamated, the family business. Construction and shipping are it's two major areas, and business has of course been bad. Desmond has been reported as becoming more and more erratic as the company's balance sheet looks worse and worse.

Patton's oldest son, Osmund Cobblepot was a well-known drunk and philanderer in the good economic times of the 1920's. He was well-know as a complete mess and embarrassment to the family. One time, he was so drunk during a speech in front of some bankers who were to fund a new bridge and tunnel system from the North that he told a story about his sexual escapades with a farm animal which created a huge stain on the Cobblepot name. Since prohibition ended, Osmund has disappeared. He spent a lot of his time downtown in Chinatown at the Dragon's Den, and when his disappearance was confirmed there wasn't much of a reaction from the family other tha relief.
