ANNAPOLIS, Md. —

Authorities were searching for the daughter and a grandson of former Maryland Lt. Gov. Kathleen Kennedy Townsend on Friday after a canoe they were paddling in the Chesapeake Bay didnt return to shore.

Gov. Larry Hogan identified the missing relatives as Maeve Kennedy Townsend McKean, 40, and McKeans 8-year-old son, Gideon Joseph Kennedy McKean.

Kennedy Townsend, who served two terms as Marylands lieutenant governor, is the eldest daughter of the late U.S. Attorney General and U.S. Sen. Robert F. Kennedy, and niece of the late President John F. Kennedy.

I reached out to and spoke with Lt. Gov. Townsend this morning and on behalf of the people of Maryland I expressed our most heartfelt sympathies and prayers to her and to her entire family during this difficult time,” Hogan said.

The search started Thursday afternoon after the state Natural Resources Police responded to a report of two people on a canoe in the Chesapeake Bay who appeared to be overtaken by strong winds.

A statement from the agency, which didnt name the missing people, said they may have been paddling the canoe from a home in Shady Side, Maryland, to retrieve a ball and couldnt paddle back to shore. An overturned canoe matching the one used by the missing people was found on Thursday night, the agency said.

News of this tragedy hit me and my family hard this morning, said Anne Arundel County Executive Steuart Pittman.

We are holding Kathleen and her family in the light, and holding our own loved ones a little closer as we reflect on their pain and their loss, he said in a statement.

The Maryland State Police, U.S. Coast Guard, and local police and fire departments joined in the search.
