Ransdell's great-great nephew was the New Orleans entrepreneur and philanthropist David Ransdell Voelker. Following Hurricane Katrina, Democratic Governor Kathleen Babineaux Blanco named David Voelker to the Louisiana Recovery Authority. Blanco's successor and past opponent, Republican Bobby Jindal, elevated Voelker as chairman of the authority. In 2008, though he had been identified previously as a "longtime, diehard Republican", David Voelker was the largest donor in Louisiana to Democrat Barack H. Obama of Illinois, having given the then neophyte presidential candidate $80,000, according to the nonpartisan Center for Responsive Politics in Washington, D.C.
